I have an old 416 TB, need wiring help.? It currently has been wired for use with? the PS-4 switching box,,, instructions say that as wired, it will be LHC when not energized,,,? RHC only when energized. I want the opposite,,, RHC when NOT energized.??? (I am not going to energize?? --? not going to use? the PS-4)
How do I wire it to be RHC when NOT energized...
?I do not have the original wiring harness for use without the PS-4.
or should I just go down to HRO and buy a linear? 432 antenna?? I need RHC or linear, i dont care which.

Swap the coaxes to the two haloves of the beam.

Hi Bob, W0DXZ
The following is the instruction manual of the 416 TB in pdf format.
http://www.cushcraft.com/support/pdf/951298.pdf
To get RHCP when NOT energized just follow the instruction in Fig-5A
The PS-4 switching box is an optional and you can wire the antenna for only RHCP or LHCP without it but you need two original balun DB part Nr 350747 and the original phasing harness PS
If you missed the above parts the manual shows you the lenght to build it using coax cable with velocity factor 0.66 like the RG-213 or RG-58
