[Amps] Coaxial rotary joints for HF

[John E. Cleeve]

Gentlemen,

 

 I have been looking at the problems likely to be incurred coupling coaxial
feeder to a rotary aerial system. There are available commercial coaxial
rotary joints or couplers which can be used from DC up to Ghz with minimal
losses. Have any members of the group had experience in using a rotary coax
coupler with their amateur rotary aerial installations.  Links to possible
surplus sources or design information would be appreciated. 

 

Sincerely, John. G3JVC / GM3JVC.
