Hi, Roger It sure seems like a lot of confusion arises when folks attempt concise electrical and mathematical thoughts and calculations using words with very broad and fuzzy definitions. Words like radial, vertical, topload, etc. can mean different things and can create remarkably confusing

Re: Topband: New Subject: 160M array feedline question

Inspect your feedline you plan to use (sounds like it is Heliax) and make sure the jacket is undamaged. If it is okay, you can bury it or just lay it on the ground and it won't matter if water covers it. Of more concern is keeping the junction where the feedline divides dry. If you use enough

Re: Topband: New Subject: 160M array feedline question

A counterpoise is what we do when the full size of a double-ended antenna, dipole, OCF, etc is too large for us to build, maintain, etc. Very simply, we want to jam the energy from the shield of our coax into the counterpoise, and the energy from the center conductor into the radiating element,

Re: Topband: New Subject: 160M array feedline question

Recycling signals at the feedpoint sounds more like a mismatch swr situation. The ground radials form half of the antenna, and that radiation from ground, in phase with the vertical radiation determines the field strength and take off angle. vk4tux On 23/3/21 11:31 am, Charles Moizeau

Hello Andy, I was on for a very short time. I worked a few EU stations with incredible signals, 599 with preamp off, on my K3 S-meter. Then the noise built up and static crashes became long and loud. The 6Y5 called me forever and I could not get his call even though I could tell he was loud.

Agree Hasse! I have not seen many real dx-ers spotted on FT-8 though. I think they´re just watching their computers. This morning, the only station I heard was VE6WZ who called cq. He was heard for 2 hours peaking 599 so there is nothing wrong with the condx! Gott Nytt År! Calle -SM6CPY
