Depends on the design of the crank-up tower... The Tri-EX CT-100 is a 100ft guyed crank-up tower. see http://www.qrz.com/db/WA3GIN for pics. You have to identify the manufacturer of the tower to dete
Yes, Crank-up towers are no different than any other towers or antennas... they require regular maintenance. The bad idea is 'not' the tower design its the idea that towers don't require maintenance.
From the description it sounds like plenum rated coax... not for outside use. We've used LMR-400 Times , five repeaterss, so far so good, been seven years in the sun on the roof of hi-rise, lots of U

Hi Folks, I've installed the Hy-gain antenna on a 60' self-supporting crank-up. The SWR curves are good and within the bands; 40m is flat at 7.255 MHz, 20m is flat at 14.200 MHz, 15m is flat at 21.30
Today, I connected the TS-480... SWR was excellent on all bands ... The MFJ was not exactly accurate... Next weekend ill try the Bird. I have a 322D but it only goes down to 25 MHz... No tweaks requi
Doesn't look like any Tri-EX I've ever seen... I have the CT-100 and I have friends that hove other Tri-EX models, on is base mounted hinge plate and the other was self-supporting with three extended

The TriEX CT-100 I use is positive crank-down and it bottoms on a pedestal. You can crank until the motor belts catch fire! 73, dave wa3gin@COMCAST.NET I think crank-ups with positive pull-down are n

I used this method on the HDBX48 and its been up for over 30 years.... funny thing is I've never had to work on the rotor (Tailtwister). I use a thrust bearing to keep the pipe weight off the rotor b

Stand-offs are a high prices accessory...great profit margin! Like you have had crank-ups for decades. Never had an issue with rotor cables or coax... Subjective opinion of one....YMMV. 73, Dave Wa3g
