A small loop mounted horizontally behaves like an E-field antenna and needs to be elevated. I tried it once out a 4th floor hotel window. Didn't work well. All the loop needs is a capacitor to tune it

Thank you Skip for the link to the loop antenna radiation calculator. I was looking for that, but couldn't find it! Are you operating your Alex Loop in a horizontal position so the null is towards you

Jef points out a couple of advantages [and disadvantages] of small transmitting loops. The circulating current will be high with any appreciable power. The radiation resistance is in the milliohm rang

The small transmitting loop, often described misleadingly as the "magnetic loop" antenna, with a circumference under ⅓ wavelength (in some applications, under ⅒ wavelength) is a practical example of a

it's called a fire stick... about 3 foot long fiberglass pole with a considerable amount of wire wrapped around it and a spring base... like you see on 4x4s being that it's SDR I can tune to and demod

Joshua - What kind of CB antenna did you get? Probably a mobile? Full quarter-wave whip, or loaded? What do you want to receive? I'm guessing not CB? For receive-only, you can use almost any piece of

I have an SDR dongle and I just got an MCX to SO-259 adapter.... The dongle is receive only, I have a CB antenna, will that work? Do I need to impedance match if I am just receiving? Can I use Rev.C c

I decided to mount the SO-239 to the chassis. The mod was easy (vid to come), the original plug was not in great shape and this radio has already been modified so I am just going for it. I am much mor

Saw the video. Great start. May want to keep the RCA plug for the ant. connection. Soon as you start drilling holes in the chassis, the value goes down. Appears you have the opportunity to restore to

Apparently the answer to your question is "no," you couldn't embed the video. Meanwhile, I enjoyed your first video about the Sixer. I haven't seen one of those, or a "Twoer" in years. My recollection
