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

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

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

Topbanders Thanks to all who responded I received a lot of good advice and will be taking it. Specifically, the advice to bury the hardline rather than elevate it. Some brought up the idea of my ground mounted radials becoming submerged in fresh water...however, that would only take place

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

If the radials have a good chance be being submerged in fresh water, I would consider elevating the radials. Had an experience here where my 40 radials on each of my 4 square verticals were often times below the water level and radiation efficiency dropped like a rock. Great receive

During the past week I have been surprised by the good propagation between FL and EU. I have a noisy home QTH and do not have an RX antenna now (rebuilding it). The noise on the TX antenna here is S8. Many EU stations were well over that and the QSO-s were easy and pleasant. Very rare from

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.
