Many people have described observing this anecdotally, like W0UN with his 50 to 100-mile view in Colorado, lighting strikes would cease when they neared his antenna farm and pick up again a couple mi
Does anyone have information on splicing telephone poles? I understand W6AM did this to get more height and I think I've heard of others doing the same. 73 - Rich, KE3Q ______________________________
When I was a kid, I used a standard hacksaw, then deburred with a round file. Worked fine. 73 - Rich, KE3Q I have used small milling bits chucked into a normal drill press before. An economy type dri
What's an FOM? And, for us non-engineers, bottom line, can we still safely say more efficient antennas with more gain are going to tend to be better, in general, than less efficient antennas with les
Here's a real-life anecdote. VK0IR, Heard Island, was on the air. He was on 20M where I had a 6-element monobander, 46' boom length (Telrex) at 120'. A friend of mine near Philadelphia -- I'm in Mary
Besides, trees are, indeed, one of the sources of air pollution. I'm not joking. - KE3Q _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "W
Yes, I've bought them at Home Depot several times, 500' roll, insulated, 14 gauge. The insulation is black, at least on what I have bought. I can't remember if there were other colors. It was less th
Okay, I should be in Home Depot in the next couple days and will report back on the current price in Bowie, Maryland. hi. I have a few spools here in the hamshack. It is labeled "14 Black solid coppe
I did this some years back for Field Day and found it worked great. I had a 2M J-pole made out of copper plumbing pipe. The pipe did not have caps on the ends, top or bottom. I threw a rope over a ta
As I often do, quoting others more expert than myself, the main issue seems to be detuning of the 15M yagi by the 40M yagi. I asked W3LPL how far a 15 and a 40 should be apart. He thought 30' would b
I agree with the other commenter. I had talks with Nextel some years back about installing a Rohn 80 on one of my properties, as a cellular site. And K3ZO has one up, in a suburban backyard -- with 3
Many people who have horizontal loops have them low, which is thought to be good for a big signal close-in -- some of us have experienced having trouble working close-in stations with antennas that a
I believe at below half a wavelength, the performance of a fullsize antenna should outperform a reduced size antenna at the same height but be inferior to the fullsize antenna at a half wavelength ab
I believe a full wavelength loop is, in fact, a "quad," a single element one. And, I have stated before my real-life, factual, empirical observation of yagis 8/8 Telrex and quad (4-element "Skylane")
Anyone have the dimensions for the popular Cushcraft 5-element 6M yagi? I have one here that I got used to begin with, had it out on loan, got it back and am putting it up -- it appears the second di
Thanks N3PKC, within minutes, with this address, which I assume will cover it: http://www.cushcraft.com/support/pdf/a50-5s.pdf 73 - Rich, KE3Q _______________________________________________ See: htt
Anyone know how far the "extension" anchor points are from the base on an AB-577 portable tower, military surplus? The anchor points for the first set are in the manual and can be found with the tria
I know of plenty of real life stories of a guys who pays a lot of money for a tower. Obviously, the sky's the limit if you buy all the parts new, at full retail, and have professionals (or expensive
New hams may be deterred by the prices of new "tribanders" these days, $1,000-plus. Although I have seen a number of new hams who "turn up their nose at" buying anything used ... (one "older" ham I k
Anyone having a custom home built might consider seeing what it would cost to have your builder add "hard points" on the roof, with mounting antennas there in mind. It could go so far, depending on y
