[TowerTalk] Rotor Cable UV, etc., resistance. DAVIS RF Re: TowerTalk Digest, Vol 204, Issue 7

[Steve Davis | Davis RF]

Hello T Talkers and  Elliot,

Belden 9405 is not only expensive, it is a PVC jacket.   There are numerous compounds of PVC and not all are  acceptably UV resistant.  DAVIS RF uses
PE outer jackets on all of its rotor cables.  We were the first to do so in the ham market.   Not only is PE highly UV resistant, it can be buried (the type of PE that  we use) and is resistant to oil, gas and certain chemicals.  Same jacket as I designed/used on  Bury-Flex  (Tm of DAVIS RF) which is also fully submersible in H2O or salt water (no data to beyond 100 ft. depths).  And DAVIS RF rotator cables are economically priced, no major price difference for PE outer jacket.      73, Steve,  K1PEK

My antenna refresh project is moving along.  The Orion 2800 was installed in 2007 and has functioned flawlessly.  Since I am replacing the coax it dawned on me that I should also replace the rotator cable.  Can?t  inspect the condition of the jacket etc but probably needs changing.

Suggestions on sources would be appreciated.  Orion recommends Belden 9405 but I definitely need cable that is very UV tolerant here in Southern California.

Thanks es 73,
