John A number of tuned loops connected together would not sum as you describe, it would be a vector sum that would be very dependant on having every loop exactly tuned to the same frequency so that

Thanks to all who replied to my original post. As most of the replies mentioned, phasing the loops will be the main issue. I have tried to address this by stacking the loops vertically such that the

Anyone tried a calcium carbide cannon to launch ropes to hoist up antennas? I built one out of ABS pipe and fittings with a BBQ igniter, and a charger from Big Bang

good luck still to cold here to mess with antennas yet? ?but pre planning some small tower stuff for the six meter cycle coming. 73 Murf

Ah also, The tuned loops are higher Q than broadband loops and they will interact. I have experimented with two tuned loops parallel to each other, and only one needed to actually be fed, as there

Hi John. I tried that some years ago. I already had a Pixel loop which is really outstanding. I got another one and placed above the original by about 1 meter. (some day I'll try this with a

I think you may encounter some problems with the physical spacing and the feeds simply being connected in series. However a similar technique is used a lot with active broadband loops, so in theory it

Good afternoon all, Has anyone had experience with stacking multiple relatively-small tuned loops as a means for increasing the effective height of the resulting array without violating the

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
