Question About Tuning Diodes
Hi All..... I have a question that I hope someone can help me with. I am planning to build an outdoor remote tuned loop antenna. I have read that you can find tuning diodes in the range of 40 - 700

You might want to email him directly.
That is a very good question, BTW.

Re: Homebrew Butterfly capacitor, 12,000 volts!
What is the lowest capacitance on one of your kits, along with the max. I
keep seeing the highest being listed but nothing about the low end. This is
important to me because I have one loop that works

Re: Trask Amplifier for Wideband Active Loop Amp - mod suggestions?
It's actually fairly simple, and can be accomplished with a few modifications. First, break the connection between T6 and C20, then connect your power line to C6, Q6, etc. to complete the supply

Trask Amplifier for Wideband Active Loop Amp - mod suggestions?
Hi Team,
I'd like to try out one of these amplifiers on a 1.8m aluminium loop I have built. Not sure if the designer Chris Trask himself has time to answer questions right now, but I thought I'd put

Re: Bye-Bye Loop, Hello vertical (for LF & MW). . .
I believe the balance of a small loop antenna is indeed the key to get its
figure-8 pattern with the nulls. That, along with the metal roof might
explain why yours didn't show any, and why it got at

Re: MFJ 1788 SWR readings
OK, I'll be waiting for the pix. You might include some descriptive-words
that identify anything that might be an interfering conductor. Good luck .

Re: MFJ 1788 SWR readings
Hi - Include a picture looking at the building where the antenna is
located. It may give us an idea
of what might be causing your antenna detuning.
