The primary advantages of high impedance verticals are - very; /archives//html/Topband/2023-03/msg00032.html (10,487 bytes)

Be sure you very effectively waterproof all of your coaxial cable connectors that carry DC power. Even the slightest amount of moisture in t; /archives//html/Topband/2023-03/msg00033.html (14,316 bytes)

Equally important on any outside electronics is to very carefully clean ALL the residual flux off the PC boards, and especially on the F-conne; /archives//html/Topband/2023-03/msg00034.html (16,970 bytes)

Re: Topband: 2-element receiving arrays (score: 1): Author: VE6WZ Steve <ve6wz@shaw.ca>; Date: Fri, 31 Mar 2023 17:34:41 -0600 (MDT); I received a few private emails asking similar questions about my power redesign of my amps. I need to clarify this. Yes, I have redesigned a version of a HI-Z amp that does not use 12v on the coax.; /archives//html/Topband/2023-03/msg00039.html (20,049 bytes)

One point of clarification: now that the 12V is not traversing the coax, what power source are you using? Solar panel + battery, or other? 73, David G3WGN M6O I receive; /archives//html/Topband/2023-04/msg00000.html (19,098 bytes)

Depending on length, this can cause significant unwanted impedance transformation. 73 Frank; /archives//html/Topband/2023-04/msg00003.html (11,461 bytes)
