Sometimes things get off topic, but my delete key works real well, and unlike another list I read, folks who try to post something that the admin doesn't agree with are not censored. Hint -- the othe
All of my email has forwarded to the same address (@mit.edu) for the past 10 years, so I'm on a lot of spammers' lists. When I used Eudora, I used a local filter called Mailwasher which worked well
When cutting phasing lines for my RX antennas I always measure the velocity factor accurately before precise cutting. I had previously measured a 500' roll of Vextra RG-6 (non-flooded) purchased from
W1KSZ: and what kind of antenna(s) you use it with. How well does it work ?? I've been using one for ~1 month with a pair of Beverages for null steering to the backside. It works very well (after dis
K6KR: < EHS is a lot cheaper than Phillystran. How much of the 75' guy should be Phillystran for 'good' HF results? The antennas are the tower are on 40, 20, and 15 meters, and the booms are about 48
obvious. MAYBE, just MAYBE, the patent covers the use of a 'wench' in the design. Or maybe a North facing plastic owl (SORRY!! I couldn't resist <GRIN>) Why not patent a good idea that's been in the
Should have added the following description to the radial plate link: "Covered by a US Patent, this feature assures a direct connection from your coaxial cable shield to the radial system for the mos
K6UJ: for a 15 meter yagi for 6000 miles. Your question depends on many variables. There are two programs that you can use to help answer your question yourself: 1. What angle is optimum? Depends on
W9AC: Been trying to model the legendary W3CRA site using HFTA. I did that about 10 years ago. The following includes some interesting anecdotes and photos as well as HFTA: http://users.vnet.net/btip
In today's age of precision GPS mapping to a few feet (or less) and computer augmented displays, why wouldn't GPS location be sufficient? Looking ahead to thousands of drones delivering packages, I'd
10m is not 20m but I suspect the same effect applies: "Using only the 45 degree azimuth, below is a plot of my takeoff angles for all 3 antennas ( ), the bottom two ( ) and the bottom only ( ). I oft
25G? If you can find one, a KLM 1500HD (no longer available) will fit into a tapered top section of Rohn 25. I know because I just tried the one I have in 25G. You have to mount it in a 25AG series
K8RI: > A heavy duty rotator with a large antenna should be mounted well down into the tower. Mounted at the top, in the tapered section would likely put very high stress at that point. I mounted my
rotor to ramp up or ramp down and when it starts turning, it does put a good bit of twist to the tower, even with anti-torque arms. Same applies to stopping, when it stops, there is no slowing down,
