VE7RC: I also have been doing that since I got into this crazy hobby. I hate saying it but that was around 1960-61, geesch, time flies when your shooting sinkers over the maples and chestnuts. I did

Great idea. I'm going to put one of these together. 73 Tom

Pat, Interesting that you find yours works well at 20 feet high. This doesn't surprise me. Modeling shows how different the performance of loops can be at different heights. According to EZNEC, a

Frank, Though Bob's youtube presentation is interesting, it is way overkill for my situation. The difference for my situation is I have lots of? tall, skinny evergreen trees. The problem with these

Murray I have one for 160 m. I feed it with ladder line to 1 to 1 balun then coax to the inside of the house. my favorite antenna. Mine is only have 20 feet and does well on 160 in the USA. On the

Hello Frank I just found your note about a dog-toy launcher-device and wonder how far/high it can lob a weight and throw-line. website for it ? Thanks for additional info. 73 Dick/w7wkr at

The length and height sound good I never had much luck w the sling shot approach.? ?Even wrist rocket was lacking in performance.? ?I now use a dog retrieval training tool per Bob Heil's YouTube

With further consideration, I think the loop is more likely to be a rectangle as follows: two sides 165 feet, two sides 357 feet. I don't have enough space to make it a 261-foot square. Murray

I've been away from this subject and this group for a long time. I am building a new house and I am now planning a loop. I want the loop to be approximately a square with each side about 261 feet

Hi Mike, Ah OK, that clarifies several things. I think that it is important to include that information in more detail along with your design. Your design decisions then make a lot more sense when

Hi Martin, I agree, the input capacitor of 1nF is too much in most cases. I used this value with cross-parallel loops 0.7m diameter each, copper foil conductor on kids hula-hoops. The combined

Hi Bob, I'm pleased to hear that you found my notes of interest, however the credit should really go to Owen Duffy. https://owenduffy.net/blog/ Who was the person who originally inspired a lot of

Hello Martin:<Off topic, but kind'a relevant.> Your reference to G8JNJ's article is appreciated in a timely manor. Due to its clear and basic explanation, I will probably include it in our Level-1

Hi Mike, A good project. I'm a bit concerned about the value of the input capacitors which are shown as being 1nF, with a comment to reduce them to 100pF if there are no strong FM stations

Alan, Thanks for the time you spent on your extensive write up. Much appreciated. To answer your questions/advices : 1. There is a steel reinforced concrete floor between the Baby Loop and the

Not so much a propagation concern as keeping the near fields away from people. The voltage on the tuning capacitor will be of the order of many kilovolts? with a current of >10 Amps at around the

I not put anything near the loop. I would only build something below the loop. A platform of 1.5 high where the 2 meter pool is standing on. And then the loop will sit on the pool. The loop will then
