321. Re: [TowerTalk] Install Type N connector to 1/2" Smoothwall (score: 1)
Author: Steve Maki <lists@oakcom.org>

Do you have Heliax or smoothwall cable? Heliax has a corrugated shield. There's no reasonable way to install JMA/PPC compression connectors without the Ridgid compression tool set, which is around $4

Kind of vague John, but here: LMR400 style 3/8" cable is suitable for many applications. If it's suitable for YOUR application, I can recommend the Shireen 400 knockoff at around $400 for a 1000' ree

Point taken about the OP's subject line. However at this point in time it's hard to come up with a reason for sticking with RG213, except for rotator loops perhaps, since LMR400 is a superior cable.

Depends on: 1) How badly the pieces are fused. 2) How valuable the pieces are. 3) How much patience you have. I had some stuck aluminum tower sections that I spent considerable time on many years ago

I've handled this situation a couple different ways. I usually like to keep the equalizer plate(s) a little higher off the ground, so use a couple of 3' long parallel angles or plates, attached with

In general, the taller your height requirement, the more you save as a percentage of cost with a guyed tower. Very short SS towers (60' is in the very short range) are cost effective, saving you the

How many bolts? Obviously 10 bolts will have 10x the strength of one, including pull out strength. Most SS towers are designed for fewer large bolts rather than many small bolts. Part of the reason f

Yep, because closely spaced bolts can more easily pull out a *chunk* of concrete containing all the bolts than widely spaced ones. I was thinking of bolts *slipping* out of the concrete. -Steve K8LX

An adjustable mast clamp is good, but doesn't solve the fairly common issue of the rotator not being centered in the tower (or not lined up with the upper collar/thrust bearing). A neat solution is t

Only if you use too-small thimbles. Properly sized thimbles for your properly installed big grip will be...just right! Big enough radius so it doesn't fall out, and strong enough to not compress from
