Hi Why not contact Andrew directly and see what he says?? He is a very reasonable man whom cares about his customers though out the world..( not just here in 40degree c England ( yes it was 100f plus

Hi Ed Disagree on a few points there. But best tubing I have found is air con tubing or if you can get 2 inch heliax coax..but if air con Not china made! Ali at best has twice R of copper. More

I lived in Arizona before moving to Oregon and have had 3 modules fail in about 15 years, probably from heat. Andy has been kind enough to replace them when I asked about the failure. I cover the

Hi “Spending a lot of money on large copper pipes for the TX loop results in high Q, which causes very narrow bandwidth, and limited power handling. Much better to make the loop larger and just use

Which group is discussing Q meters? I assume you are talking about transmitting loops. Litz wire in general, doesn't do much for frequencies above 1 MHz or so. The only ham band where it could do

I agree, the Florida, Arizona heat problems destroy most outside use electronics. This is especially true of products designed and used in European countries. They do not take into consideration that

I am on my third Wellbrook replacement loop head. It appears that the potted resin is not only keeping water out (amongst other things) but seriously keeping heat in. The heat buildup in Florida is

Dear Jinze and other members: Please,have a look at https://www.microflex.org/index.php/en/magnetic-loop-antenna-amp-en for my attempt for a open source version of the LZ1AQ amp. 73, Andre, pa3ajr

Watching the discussion about Q meters in another group. I see people here sometimes building loops with copper pipe or litz wire to reduce losses. What about actually measuring Q? I have some ideas

This man is a liar, the antenna he sells on the second-hand market in China is a joke, many Chinese hams are also deceived, there is a false propaganda appearance, his name is "Goku Antenna", I want

Thank you Steve, for this valuable Information. It might well be, that both dies are from the same manufacturing plant. I like the PZT2222A and PZT2907A for their robustness and use them in active

A small loop - <10% circumference of a full wavelength at the highest frequency of interest - exhibits the nulls in both directions perpendicular to the plane containing the loop. So, laid
