George, Looks like LMR400 is the winner...Thank You for your input. Tad, I was thinking about the students in terms of their work in setting up the supports for the temporary antennas. I'm thinking we should go with a sealed wooden platform/low-profile box that can be held down with sand bags on the roof or affixed to the trailer. These "boxes" may need to be replaced in a few years, but the students will have designed and fabricated them. Jojo, As soon as you know which day you'll be working at HRO, let me know so that I can contact our Booster's Treasurer so that she is ready over the phone to make the credit card purchase. Everyone, I know that swap meets are a cheaper way to get components, but if there are any issues with the purchase, we don't have the warrantee behind the purchase to get them fixed or replaced. With this is mind, I'd like to ask for suggestions for a 70cm /2M radio and a 10 meter radio. Dave has loaned us a 10 meter radio for now, but I'd like to be able to return it as soon as possible. Also, in terms of the grant budget, we have a lot to purchase. When I wrote the grant, I use the HRO Catalog and found approximate prices to create the budget, but did not get down to actual item level. If anyone would like to offer suggestions for the items detailed in the budget, this will make our purchase much cleaner. My suggestion is to reply to this email with RED lettered suggestions next to each item you suggest.

They are very expensive and it is very stiff (not unless you're going to buy the LMR600 flex which like buying gold pieces). If the plan is to run it into conduit again LMR600 is not good for the project. I have used LMR400 times microwave coax and it is a very good and very easy to manage. I also would like to suggest to have a 10 meter antenna in The shack. Or maybe a multiband dipole's. Thank you. George ke6te

Hi Eric, These are very good illustrations! I will invest on good brand, low loss, flexible coax cables. I'd suggest LMR600 from Times Microwave for the 150 ft run. If budget permits, it can be LMR600 for three coax runs. Otherwise, I'll settle with LMR400 for the medium and shortest lengths. How do you manage to put a coax in and out from a conduit of such great lengths? Is there a guide wire that you use? Other hams can surely weigh in about the coax feedline. The portable shack location appears perfect. We can put the VHF/UHF radio antenna directly overhead. These radios usually run no higher than 80 watts. RF energy exposure should be within correct limit. The West Mechanical well area or roof can have the HF antenna. HF radios are typically at 100 watts RF power, and some go up to limit of 1500 watts with amplifiers. It can be a future experience running or acquiring those QRO (high power) capability, if at all necessary. 100 watts is almost always enough for most of us. HF antennas can also be big and wide so the farther it is from the operator, the better. The HF antenna can be on the West end. If we are starting with just VHF and UHF, I think we don't even need the 150 ft coax length now. We can focus on coax going up to the East Well roof and coax going to the transformer pavement. Two (2) runs for each conduit so we can separate VHF from UHF (thinking about separate VHF and UHF antennas for satellite work). 73, Jojo KN6HTD

1st Meeting at Laguna Creek High School GETA Building January 21, 2023 1pm to ~2:30pm PST Attendees: In-person Eric KN6TNH Students: Ares V., Rosa H., Olivia P., Ace D., Jason N. (please write down student names here) Parents: Sean O'Brien, Tad Hashimoto Jojo KN6HTD Dave KK6MVJ Chris N6ICW Zoom: William Zaggle KC0KSR, Darrel KM6KFW, Rosa Haidari KN6WEF View the Radio Club Working Group Directory (Spreadsheet), with Attendance Record in Google Drive Minutes: Introduction of participants Presentation of ARRLGrant Narrative by Eric Tour of the Building and Rooftop Initial discussion about antenna construction and placement of the ham shack Plan to start the purchase of review materials for amateur radio technician licensing Photos: View all Photos in Google Drive Interior of the GETA Building. Eric KN6TNH is the presenter. 1 parent, about 5 students, 3 hams from clubs are present in-person. About 3 participants are on Zoom. The GETA Building has two wings, the R and the L (Eric can describe this best). This is one rooftop where an antenna can be built (one of the options). Discussion: The local amateur radio clubs are thankful for this partnership and collaboration The students are expected to study, take the exam, and get the license for the Technician Class Amateur Radio operation Review materials for the students will be purchased Discussion points Questions, suggestions, or comments Next steps/ point person Local amateur radio clubs are thankful for this partnership and collaboration Mentors are what will guide this vision to success. Invite 2 more hams who have done satellite tracking and QSOs with ISS astronauts (Jojo can help) 2. Get the education and test prep done How did one of the students get the license (Rosa KN6WEF)? Answer: Rosa, on her own, studied The ARRL Technician Class License Manual and took the Tech Level test online. Suggested materials are Gordon West’s Technician Book and Ham Study.org phone app Order Review books and get the HamStudy.org phone app for question bank and answers review (HRO thru Jojo) 3. Get the licensing done ARRL VE team can be invited to hold the ham exam in Laguna Creek High School, in person. Or, online via GLAARG Sierra Foothills have digital testing in-person platform now. Other VE group uses pen and paper GLAARG is fully remote - sked can be seen in hamstudy.org Where will the shack be? Just under the antenna installation (conduits are available on either side of the building) We, the GETA Program, have a discarded computer cart that will function as a portable shack. 5. How will the antenna tower be built? 6. How much weight can the rooftop bear if antenna is mounted on top? A.Either starting from the ground B.mounted on the rooftop On Monday, Jan 23, Eric will reach out to the EGUSD District lead in Facilities to find out what sort of antenna mounting options will be accepatble. Research into what other schools have done must be completed so options can be given to Sue Bell in Facilities. Those who have experience building antenna masts or towers can submit propositions here and take the lead of the construction when selected 7. How can a low power repeater be set up? Something that can also be made portable for field exercise and demonstration? The goal is for students to understand the process and see the hardware work (not to demonstrate extreme long reach) Yes, at first, a proof of concept/low power portable repeater will be built either with donated or purchased components and parts. If we find that we want to further pursue a more robust version, we can upgrade as appropriate. The point person will most likely be Chris N6ICW as he has extensive experience with repeaters. 8. Purchase of the CanSat (ongoing) The paperwork to purchase our first CanSat from Twiggs Space Lab has already been initiated Eric KN6TNH will be the point person on this. 9. Purchase of the radio equipment Ham Radio Outlet Employees, and local HAM Elmers will help us identify and purchase our first shack components Eric and Jojo will work together to get the initial system's list created and purch

From: "Eric via groups.io" <ejjohnso@...> Date: January 23, 2023 at 09:57:28 PST Good Morning Everyone, Here is what I found from the head of Facilities here in the Elk Grove Unified School District. If we stay off the roof and under 30’, DSA does not need to be involved in the construction of the antenna. So a ground mount at 29’ 11 and ?” is what we will start with. Not ideal, but we have the go-ahead with these parameters. With this in mind and the vision to expand in the future, what is out there that meets these requirements? Thank You Everyone, Eric (KN6TNH)

Hi All, I did some digging and discussed with a couple Ham nerds and discovered that compact UHF/VHF antennae that cover frequency bands in the Ham Technician License range are very easy to either build or purchase. A simple J-pole antenna covers a couple UHF/VHF bands for local use, and can transmit and receive in a large donut-shaped area around the vertical antenna. A quick search for "J pole antenna comes up with a lot of inexpensive options. Arrow Antenna has some rather stout models that could be clamped to a pole mounted to the inside of the roof well. The same thing could be built using aluminum tubing and some welding rod. The antenna would be ~60" tall, plus the height of the pole it would be mounted to. Connections would be simple coax cable run to the roof. HF coverage would appear to require a larger antenna that might be harder to set up without stringing the antenna wire between the two roof wells. Doable, but less storm resistant. HF is what you'd want to use for really long-range communications (other states/countries). The satellite antenna is a bigger project. I suspect there will need to be something akin to a computer-controlled telescope tracking system attached to a much more directional antenna. I haven't done any digging yet, but I'm reasonably confident that a solution exists. I'm not sure what kind of communication system the satellite will be using, though. Microwave? The communication frequencies would dictate the type of antenna needed. -Tad H.

Happy Wednesday everyone! I'm sure everybody is thankful for the sunny skies and break from the rain. We can meet and greet more comfortably this Saturday, January 21, at the Laguna Creek HS. I just created a spreadsheet to put our names in for the attendance. Eric, I suppose an agenda will not hurt but I am only expecting that we can see each other in-person, introduce ourselves and our background, review our goals, see the campus and the future site of the radio station and come up with TO DO items. In which case, I will be happy to take down notes and upload it in a Google Drive. 1 hour to 1.5 hours could be enough for our meeting time but you will certainly be the captain of the show. Are we seeing any of your students? Any instructions about parking and entrance to the school or meeting venue? I will be in Ham Radio Outlet on February 1st and I always help anytime but transact anything for purchase at the store when I am there with the manager. I hope nobody gets me wrong - I love ham radio and I included selling so I can have most things about the hobby / business taken care of smoothly. I know Dave KK6MVJ is coming and James is not available. Thank you for responding to the initial invitation. Who else responded to this call for meeting? As usual, the more the merrier. I will also take some snapshots so we have images to show for further education down the road. Meeting sign-up list See you all soon! Best regards, Jojo KN6HTD ARRL Registered Instructor and VE 916-476-1688
