We tried the same antenna (full size inverted vee, top at 60 feet, ends at 20 feet) on our 20 acres. It was 20 dB down from the 90 foot vertical. Rick N6RK ___________________________________________
We listened all night long during a 160m contest to stations in all directions, near and far. The vee never compared to the vertical. It may be, that once in a while, the vee would have been useful,
Very simple. I am limited by terrestrial noise. That noise propagates only by vertically polarized ground wave. A horizonatally polarized antenna cancels out this noise. The signals are reduced, but
If your dipole seems good compared to a vertical on 160m, it is more likely because the vertical is poor than because the dipole is good. Rick N6RK _______________________________________________ __
Let me make sure I understand this correctly. A piece of rebar poking out of the concrete below grade will rust. A piece of steel poking out above grade will not rust? Why is this? Is it moisture rel
Aluminum irrigation tubing lays around in the mud all the time and never corrodes. Why would aluminum wire corrode? Did you bury it or just lay it on the ground? I wonder if a sacrificial anode syste
An anti-bird technique that has been PROVEN to work (at least in orchard trees) is to play recordings of bird "distress calls". My neighbor who owns an orchard says this is 100% effective for him. No
I have an Alfa Spid rotator and an legacy M2/Orion rotator with AC motor. The Alfa Spid guys say that you can use long runs of skinny wire to operate the rotator, and make up for the voltage drop by
That doesn't work if you have waterproof hardpan, like most of the California central valley does. The water has no effect whatsoever, no matter how long you soak it. A full swing with a 10 lb sledge
That drill is on "sale" virtually all the time. No need to rush out and buy it unless you need it now. You really need SDS max chuck. The Harbor Freight chuck is too small for ground rods, IMHO. Has
I am a Comcast subscriber, but: Comcast is very good at providing a very high speed pipe to the internet (6 Mb/s with my cable modem). I use them for what they are good at, especially since I am too
I recently bought the Little Giant 21 foot A-frame step ladder. It is adjustable in 1 foot increments and handles 300 lbs. We wanted something to use to get to the ceiling of our shop building, which
This is great information. This 075 rope solves my two complains with the usual black rope. Stretching and wind area. Rick N6RK _______________________________________________ _______________________
On the old OR2800 rotor with the AC motor, what is the motor voltage and current (under full rated load)? What is the recommended cable wire size and length? To identify a 2800 vs a 2300: The case is
My rotor has a pot not a reed switch. It is still a 2800? _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.c

Titanex seems to have disappeared from the Array Solutions site and the Titanex site shows no US dealer. What do we do now, order directly from Titanex in Germany? I just wanted some of those 5 Euro
They make non-crushing attachments for CAT-5. There is a plastic U shaped clip with 2 little nails. You pound the nails in, but the CAT-5 is only squeezed, not crushed. Rick N6RK ____________________
In this area, thieves would go into a hardware store and grab a roll of copper wire and run out the door with it. They now have to lock up the copper wire in a display case next to the checkstand. Ri
Comcast did not block this port until last month. Then, without announcing it, they started blocking it. I wasted a couple of hours trying to figure out why I couldn't send mail all of a sudden. Of c
