Hello friends, a quick question. When Fiberglass Rod came up a couple months ago, somebody referred us to McMaster Carr. I need some for an antenna project. Their listing says that their 1-1/4" fiber
I am looking at a photo of an ICE rotator line suppressor. Do these things have 8 ins and 8 outs? It looks like 4 ins and 4 outs to me (8 screw terminals total). What am I missing? Mark, N5OT
Thanks to everyone who responded, I got excellent answers to both questions. I now understand about the terminals on the lightEning protectors, and I also found what from multiple reports is the best
Hey guys, I got a new digital camera, so I will be posting photos from N5OT until the novelty wears off. I recall a discussion a while ago about cutting aluminum. I had to cut a 3" x .125" boom this
Hello sages of RF wisdom. I have one for you. Not being an RF engineer, the solution escapes me: I have two identical antennas on one tower at different heights. They each have feedlines coming down
This post got my attention. I have 15 ground rods to do. N5OT is definitely living on borrowed time at this point. the Any sense of the pros/cons of this approach from the ground gurus? if it's a co
Speaking of that, does anyone have a SDS-chuck ground-rod-driving-tool I could borrow to do this? (I've got the hammerdrill but I imagine there must be some tool which would aid in driving ground ro

Does anyone have suggestions for winches? I'd like to figure out if it makes more sense to just permanently mount a cable winch at the bottom of the tower for routine raising/lowering of yagis and ot
I'll throw my two cents in about K6STI and his antenna programs. I have been using YO for about 15 years to design everything I ever built for anybody. Every yagi I have built using YO has worked per
Inexcusable overgeneralized cheap shot, bud. There are plenty of crank-ups out there which provide trouble-free service for decades. Mark, N5OT _______________________________________________ See: h
Regarding the 1.5" wide copper strap that PolyPhaser et al recommend for interconnecting your ground rods - how thin can I get away with? That stuff's exPENsive! Anybody have any luck finding this in
Well, okay. Thanks Bill (and boy were you loud in the SS). So, how overkill is all that PolyPhaser reading I've been doing? Seems like 15' wouldn't go very far in their scenario - what with 3 radial
Phase Shift? This thread would have made me cross-eyed if I had studied it so I have not been following it. Nevertheless this excerpt caught my eye: I like to use AO/YO to design yagis, but I needed
Golly, I have been giving this some thought, too, for the past 24 hours. Yesterday I was getting an antenna ready to go up for CQWW and had a stupid mishap which resulted in a bash (with bleeding) to
Not so easy; the station is a 20 minute drive away from home and she's generally not available at the times I do the work. There may be a bargain to be had there, though. We'll see if she brings it
