My PP is mounted to a modified Rohn rotator mounting plate. I took it to a machine shop and had them cut a larger center hole in it. Think it 5 or 6 inch diameter. You DO need the bevel gear to make
Hygain did have a series of tribanders that used wire loops on the ends of the elements but they preceded the TH series. I'm looking at a 1957 QST that shows one in a Hygain add. It's a three element

FYI, This web site is the only place that I remember seeing information about a buried copper plate as an alternative to a ground rod. They sell a 2ft X 2ft copper plate with cable clamp that gets bu
Got to agree with Bill on this. Back in my car racing days, we had some of the "critical" hardware installed with wired bolts. They were easy to remove and re-install (no loctite) and then re-wire. N
We had one at W3GM years ago. As I recall, Gerry had 108 of 25G (10 straight sections plus a top section) on an insulated base (home made). He had a 24 ft length of aluminum tubing (2 inch) out of th
A week or so, I promised to send some pix of the prop pitch indicator/control box that I built to one of the TT subscribers. Well, I lost your Email Address (W4??). Anyway, I've taken a few pix and c
I agree! This is getting mean spirited. The "true north" thread was at least amusing even though it went on and on. Just my two cents, Stew K3ND __________________________________________________ Do
They sure do! My first yagi was a home made 3 EL 20M on a 20 ft boom. All this was constructed before we knew anything about taper schedules, wind loading, etc. As I recall, it used only three sizes

I have a 75M inverted vee that I rarely use for DX or DX contests. Before I had my vertical installed, I used to use an alligator clip with about four feet of wire and a relatively heavy insulator on
I'll have to agree with Val. Usually the problem turns out to be the last thing you worked on before the problem developed. Been there, done that, face red... 73, Stew K3ND __________________________
That's correct Tom. I got to thinking are I remembered that W3GM used to have 3 or 4 sloping dipoles for 75M on one of his 100ft towers. As I (now) recall, he used to add a 7-8 ft piece of wire to th

I spent over three hours up on my tower this past weekend. It was sunny and warm (70's) so I decided to do some upgrading of some cabling and general maintance. We won't be getting too many days like
I intend to cover all bases. I just mounted my plastic owl on one of my newly polished elements and aligned him due north. Used the "beak shadow" method. (sorry, couldn't resist!) 73, Stew K3ND _____
