Would appreciate latest thoughts re best coax type for a 55 foot crank-up tower with the coax and rotor cables suspended (Kellem) from the top stand-off--OR-- does anyone recommend attaching cables t
I have the HDX-555, but the principle should be the same. I used BuryFlex from Davis RF (www.davisrf.com) and have it suspended from the top standoff using a Kellem Grip. When I lower the tower, I le
I have the same combination: TX-455, 3-element SteppIR; also Ham-IV rotator, a terminated inverted V (a few feet below the top) and a half-sloper (at top of second section). I let the coaxes and cont

theory that the sliding joints and steel cables may not have the best connections. The connection reference was for good RF connections between the tower sections. This would seem to be important fo
Om my US Tower, I use a 90 degree PVC sweep in the top stand-off, held in place with 10 or 20 mil thick pipe wrapping tape. I tape the cables to the standoff arm before they enter the sweep. Jim N7US
What size PVC did you use? My thought was to tape the cables along the top stand-off, then create a small loop, so they do not make a sharp bend. Then use a Kellem type grip attached to the standoff
I used a section of old, leaky garden hose bent curved to spread the weight of the coax cable. Seems to work fine with the LMR400 without sectional supports on the LM470 crankup. k7puc ______________
