Remember that the heat generated is a function on how the load (the antenna) is balanced. On an OCF (Windom) you never know. Only the common mode current is generating power loss in a current choke.

I'm spending way too much time trying to find what I need, time to ask... I need to be able to break apart my rotor cable, so I need a weatherproof M/F set for 8 conductor 18 AWG. Also I need to brea

A PL259 connector shell is ~3/4" diameter, Type N's are slightly larger. Aim for at least 20mm tubing if your meaning to seal those.-Mike-WA6ZTY From: Bill Turner <dezrat@outlook.com> To: Towertalk

Howard, I am not an expert on the Electrical Code, but I think the requirements are relaxed with "plug in" devices such as the RMC-1000. Since I devoted a conduit to the motor power, it seemed appro

Evidently they have redesigned the RMC-1000 since mine was built 10 years ago. Mine definitely uses 120V on the control lines. I had considered reworking it for 24V but didn't, I guess they did! -M

US Tower remotes and the old Tristao use 120 v to control the relays. If you have a Tri-Ex remote, they used 26 volts to control the relays. Standard rotor cable will do fine. Only use 7 conductors.

And even though the RMC-1000 switch is turned off, line noise can still propagate along the line, so for several reasons it is prudent to separate signal and control lines.-Mike From: Jim Brown <jim@

Hi Guys, Have any of you had damage to your rotor box due to high RF from Shunt Feeding your tower or by suspending an Inv. L from your tower? I get 10-20 degrees of meter movement on my Ham IV contr

A really frugal ham might make use of the rotator cable or coax for an ac extension cord. No exactly code but works in a pinch. Yes, I have personally done that but would never tell anyone! 73, Geral
