On the top pf my 10-foot tower section I have an a OFF-CENTER DIPOLE antenna (All band) when I can throw the end wires up into trees... My favorite bands in 80M and 40M...
Use to have photos of all of this but can't put my hands on them yet...
My Radio control panel is close to my wrap around seating and the radios and scanner etc are off to them self wired to the 12VDC SUB Power Panel.
The biggest problem I have is the RFI Noise being generated by my PURE SINE WAY Power Inverters... Get a loud BURRR type sound all over the HF Radio Frequencies...
