MP-1 Mobile/Portable/Pedestrian SuperAntenna for FT-817
I have the Superantennas MP-1 with the FT-817 mounting bracket and
all the other accessories. The MP-1 is probably the most versatile, and efficient whip antenna I have ever used for multi-band HF Pedestrian Mobile operation. Using the stainless steel tip and assembled for base-loading, the combination makes a very durable backpacking or shoulder-strap walking whip. With the telescopic tip and aluminum mast extensions it is perfect for compact travel carry-on packages and fixed portable setups or rental car mobile. I have recently been using the MP-1 as a vehicle mobile antenna, and have found it to be favorably comparable in efficiency to my High Sierra 1500 at 14MHz~29MHz. The MP-1 antenna is in the right place at the right time for HF Portable popularity and the FT-817. Bonnie KQ6XA |

Re: USER REPORT: DX, ANTENNAS (MP-1), ETC!!! Long Post...
Well - OF COURSE A DIPOLE WORKS BETTER - it is a balanced antenna
that doesn't require a counterpoise (or groundplane - call it what you like) and it isn't shortened with loading coils. That is ONE of the reason that all (honest) antenna performance is pretty much referenced to a dipole That being said - I have both antennas, as well as the Maldols. The ATX was the fussiest to get to resonate, but we have managed that. I have NEVER had a problem getting the MP1 to tune, but discarded those radials in favor of 4 of 17' 14 guage flexweave antenna wire (slightly longer than a 1/4 wave on 20). I have worked JA's on 40 CW on the Maldols. Alaska on 20 SSB with the ATX. Ohio from Manzanillo, Mexico on PSK31, etc, etc, etc. BUT NO ANTENNA is going to make up for propogation - especially with a 5 watt radio. NO ANTENNA is going to tune the same when the environment surrounding it changes. NO ANTENNA that is physically shortened with small diameter loading coils, especially one at the base of the whip, is going to perform like a full size dipole, even if the dipole is olnl a few feet off the ground. During the mid 70's, I used to carry around a HW7 and a 15 meter dipole that I would throw up between some trees in parks around Southern California and get on CW during a lunch break. I practically had to beat the JA's off with a stick! But the point here is I for one am tired of everyone whining that this antenna or that antenna doesn't work as well as a dipole - OF COURSE IT DOESN'T!!! It is the LAWS OF PHYSICS and there is no way to amend them. You have to comprimise for convienience! If you find this all baffeleing - get a copy of an Antenna Book from the ARRL or RSGB and READ IT - don't just put it on the shelf and admire how nice it looks there. If you REALLLY want your eyes opened, get a copy of Moxon's HF Antennas for All Locations from the RSGB. I probably have well over a dozen and a half antenna books, and EVERY one has SOME valuable tidbit in it. I've been doing this stuff for damned near 40 years now, have made a somewhat sucessful business out of HF SSB in marine applications, but hardly a week goes by when I don't learn or discover something new. BUT IT ISN'T EASY - THIS STUFF CAN BE TOUGH AND CAN TAKE A LOT OF TIME AND EFFORT TO MAKE IT WORK RIGHT - BUT IF IT ISN'T WORKING RIGHT - NOTHING IS GOING TO HAPPEN. I HAVE MADE SOME OF THE DUMBEST MISTAKES WITH OVER 100 YEARS OF COMBINED EXPERIENCE LOOKING AT THE PROBLEM - BUT THAT IS HOW YOU LEARN!!! --- In FT817@y..., harry.edwards@s... wrote: --- In FT817@y..., julian@t... wrote:telescopicWell, I spent USD 225 on the MP-1, 80m coil, tripod and awhip, plus about 40 quid on VAT and duty when it arrived, and Ican'tuse the thing at all.

Hi Arian. Any accessories from the U.S. or Europe are much more expensive

here. You might find some Japanese antennas slightly cheaper, but there will be a greater variety than you are likely to find in any ham store in the States. The Japanese bands for both HF and VHF/UHF tend to be slightly different on the freq ranges so you likely want to avoid buying rigs here for overseas use. (Singapore is more of a bargain and the ht's sold there under the counter are usually 'snipped' to give total coverage outside ham bands too). There are a number of stores in Akihabara devoted to ham radio (or primarily ham radio) but the whole area is a maze if you've not navigated it before (we don't have traditional street addresses here.) The Akihabara Ham Shop Association puts out a map in Japanese which is titled (in English) "Enjoy Ham Shop Guide." When you get to Japan, drop me an e-mail with your hotel fax number and I can fax it over to you. If you're good at reading maps, you likely can do a decent job of navigating even if you don't know Japanese and if you stop people and point at the map, they will be eager to point you in the right direction. 72, Steven 7J1AIL K7USJ cq@... -----Original Message-----

Here at my office highrise box, the window doesn't open. It's a new building, double or triple paned with lead I'd imagine. I can barely hear anything on the '817 at all on HF at any time -- a few SW broadcasters and faint WWV from time to time. It's amazing considering that it's on the 32nd floor but there's a lot of glass surrounding me too from other angles of the building. From home, on the ground, with a groundless MFJ vertical up 15m from an antenna tuner all is fantastic as well as on the road, so I know it's the QTH not the rig. -----Original Message-----

Just curious Steve, with the heavily leaded glass what is your signal strength with the rcvd sigs with window open and closed? I have been frustrated a few times with my "Motel Mobile" ops in great reception but unable to "get out" I did not consider the "glass factor". Are all the "leaded" glass tinted or can they be clear also? I have found that with the MP1 on the tripod with the counterpoise spread as well as I can get it to be the best. I tried running an alligator clip to the window frame a couple of times and had troubles. This is with the MP1 sitting in front of the window frame, window sealed. Most of the hotels do not seem to have opening glass anymore. Thanks for the input, since this is about 50% of my ops now. Paul KB8VWV |

QRP. One very significant and major difference between these loops (bent 1/2 wavelength) and the MFJ and AEA loops is that the MFJ/AEA loops are very small (36 inches) and are considered magnetic loops, not like the larger electrical loops. If your planning to go portable with the 817 and a loop, You might want to consider the magnetic loop. An 80 meter dual coil magnetic loop is about 42 inches in diameter!! ----- Original Message -----

is the high voltages are not nearly as high as one would expect when using a 100 watt rig! The two turn loop uses a small 1/2 inch wide by 4 inch piece plastic, 90 degrees to the plane of the two loops. By moving one loop closer or further away you can change the capacitance. Once resonance is found, lock the loop to the plastic. You should be able to do this with the FT-817 with no fear of getting "zapped" ----- Original Message -----

MP-1 and ATX

and wanted opinions on the MP-1 and ATX but I soon realized "location' made a big difference and since I am in a valley half way up the side of the Sandia Mountains in New Mexico...and no one else seems to live in a similar place, I decided to get both antennas and try them out for my own circumstances. Thank you all for your opinions, experiments and successes. I shall be re-reading the posts when the antennas come in! Jo K5HOY (near the village of Placitas) |
Re nil 2M 5 khz - it WAS the FAST button! Thanks all!
Trying to reads the manual several times while looking for 2 line
phrase and playing with the 817 setup menu can be frustating when something does not work. It WAS the FAST option enabled which doubled tuning speeds. Thanks all for your responses. Much appreciated. Jacques VE3TSC |

Re: USER REPORT: DX, ANTENNAS (MP-1), ETC!!! Long Post...
Julian:
I am curious when you say the MP1 won't work at all. Possibly I am not being as fussy but I just got off the air with a Seattle station on 30M and I am presently in Chicago on the ground floor of a warehouse with the MP1 sitting in front of the window sitting on its tripod with the counterpoise wires laying across the furniture in the room. I have never attached my MFJ analyzer to the antenna just have tuned it with the 817's SWR readout using the mike and the mode on AM. I am always able to get the SWR reading down to less than 1 bar with a little experimentation. If I use the 817 bracket for hand carry and drag the counterpoise the SWR will go up and down as I walk, but I have been able to make numerous contacts. At home I do connect the 817 up to a dipole and its performance is much better as much as 3 S units but I guess I expected that and wanted the MP1 to help out when I was on the road especially sitting in hotels. When I get home I will put my analyzer on the MP1 and report back with the results. It sure has worked well for me. Paul KB8VWV |
