For my 11 ft roof tower that I have to guy. will it make a difference whether I use Phillystran HPTG2100i or steel guy wire? Certainly there is a price difference! Thanks in advance, Eric W3DQ Washin
[Steve Katz] I'd ask: What is the tower and what will be mounted on it? Such a decision requires a "system view," not just that it's an 11 ft. roof tower. (Examples abound, but here are some: If the
You do NOT want any conductors over 12 ft long between insulators anywhere near an antenna for 10M. Note that the first insulators must be less than 5 ft from the tower to meet this requirement since
I have a photo of my roof mounted tower guyed with phillystran if anyone is interested. The tower is 15' tall with a Mosley Pro57-B at the top. Total height is 49'. 73, Ed - N5NUG
That's not quite correct. If you look in the ARRL handbook, you can find a lengths of cable that will be fine. In fact, the ARRL says that 25 feet or so is about the ideal length. As you get longer a
N4KG response inserted below. 25 That information was first published at least 30 years ago, LONG before computer modeling was available, and has been MISINTERPRETED for decades. First, there is NO S
With the exception of VS6DO's fold-over masts, every single roof tower deployed over the past ~20 years on the south China coast that I am aware of has been guyed with rope. The same 4 mm kevlar haly
That's a very good point. After having done some serious racing on 40 foot yachts, I've been amazed at the forces on sails and hardware. I am amazed at the relatively small size of bolts and so forth
SNIP HF covers 3 to 30 MHz with corresponding wavelengths of 328 ft down to 32.8 ft for 1 wavelength (WL) or 164 ft to 16.4 ft for a 'resonant' HALF WL. This means that to avoid resonance in the HF r
