Thanks for those Henry. It seems I will just ensure this metal mast is not grounded as I do not have a non conducting mast. I can isolate the silver rod from the mast (removing a DC short to its bracket - A basic Sirio GPS 1/2 ) but the mast is still conducting, being aluminium. It seems to be...

8 meters of pole, would you isolate a basic cb end fed coil loaded 1/2 wave antenna for 10 and 11m and add a small copper wire counterpoise or just direct bolt to the pole ? As this is voltage fed I imagine the risk of CMC is small on the pole. I find counterpoise such as odd concept to...

I like how these antennas look, very imposing and it seems they poke a little more signal to the horizon. Be it the old and original one or the Vector. I cannot recall what the original was called but do remember seeing them back in the day. Just 0.5dBd over a 5/8 wave though, it does not seem...

The perfect CB antenna if ever such a thing exists is most likely the 1/2 wave end fed vertical as high as possible. No radials Equals or beats the traditional design 5/8 wave when elevated to same tip height Does not suffer from excessive CMC issues in most installs due to voltage fed. Low...

That makes sense Dave as the artificial ground plane (attached radials) has gone upwards with the antenna.

A traditional well elevated 1/4 wave is no slouch on 10m/11m. It will DX as well as a 1/2 wave and correctly installed 5/8th wave. 1/4 waves on the ground for 10m and 11m is where they do you no favours at all. They will work in strong conditions but they will be outperformed with ease by a...

If the MAX2000 ultimately follows the same current and voltage distribution and matching as a traditional 5/8 wave vertical the IMAX will lose its gain as it moves further from the earth below. It relies on a good ground reflection wave that is in phase with the main lobe at lower angles, from...
