I wish I’d learned to model in the software. I have 2 different antenna programs and I’m a tard

With a field strength meter I can watch the reading go up and down based on how I turn the ground plane antenna. The meter is 3ft off the ground 20 ft away. I’m assuming that’s what your call “ground loss”. What happens if I ring the plane radials together with a wire, making a hoop basically...

It’s a vhf only mobile vertical. I can use an analyzer on it but am interested in the actual plot

Can someone with nec model a vertical mobile 2 meter antenna for me?

The first mobile test was eye opening. Station 1 is a diamond ground plane 25’ off the ground using an alinco 45w mobile as a base station. Station 2 is my mobile using a cheap Chinese mobile 25w tyt 898 radio. Simplex My rx 1/4 nmo s3 5/8 dual band nmo s3-s5 Jpole full scale My tx 1/4 nmo...

What’s the point of the coil? I can’t see where it’s changed the vertical length and it’s not a loading coil. So what is it?

My first 40ch Ssb radio. I loved it. I found another one last year and bought it. The memories were still there but I can’t seem to find the channel all the folks from 25 years ago used to run with me. Must be the radio, Not time.

Anyone want to model this?

Trimag tram mount with 102” ss whip. Testing it out later

The point of his was that it has the flexibility to be a mobile rig and hit drive thrus and banks

What kind of cushcraft

We’re pretty flat. Elevated repeaters. The antenna has no coil it’s just the curly q open air. Like the old cell phone antennas

hot an bored. so i decided to temp mount an old radio shack sputnik antenna (1/4 wave with radials) on the car as close to the same height of the mag mount thats on there already and try a test hitting some outlying repeaters. the mag mount is centered in the roof. sputnik was on the side. mag...

2 cars, both 25w fm radios. One has a cheap tram 1/4 wave quirll antenna the other a cheap tram nmo 1/4 wave. Both mag mount. Both tuned pretty close to each other according to the nanovna The do not preform the same. The quirl 1/4 does better than the straight stick. There shouldn’t be much...

Now that I have a screwdriveron my car, I notice that if I tune by watching the rx meter and max sound that the see is always higher than if I use the see meter. And I've noticed resonance is never at lowest swr. I think the swr is always about 1.5 to 1.75. It's the feed point impedance I'm...

I use a cp22e 2m base and it works well. I use a tram nmo dual band on a mag mount in the mobile does well. Hustler makes a 82 inch stick I kinda wanna try

What happens if I put a two foot riser between the mount and the tarheel effectively raising the coil section to a mid load placement vs the bottom load that it is when you install it on a standard mount? The feed point would remain the same but if I go with a 2’ stainless rod it would move the...

So no one wants to pick it up just to keep it? I paid today and can’t so if you’re close it’s yours

https://www.varac-hamradio.com/emcomm Being bored and looking for something else I started to look into digital. Tried ft8 and thats a hard pass. I found this software and thought he'll why not. Installed it and got evertrhing set up fairly easily and soon made a contact on 20m. It was a good...
