Gus, I'd be a little wary of these antennas. I, too, picked up several at a bargain price, and, after testing them, found that they had breaks in the coil that is wound on the inside of the fiberglas

Cathryn, Congrats on getting your Extra, and I'm glad you're getting excited about contesting. a 42 by 120' lot may seem small, but before you invest big bucks in a tower and beam, consider trying so
Hi Bob, One aspect you may consider is that unenforced deed restrictions equal no deed restrictions, at least as I understand it. I have maintained antennas (low profile though they are) very openly
<< Well, off the top of my head, you are claiming greater than 12.75db over the other station. >> Not true, I routinely have bumped other high power stations using QRP or low power. A good location i

Link coupled tuners have but one disadvantage, size. Generally, large coils must be used. Also, enclosures must be failrly large. I wonder if anyone has tried fabricating a link-coupled coil assembl

Gang, I just invested in my antenna systems. No, I didn't buy a tower or beam, but I greatly improved my antenna situation. Being in a covenant restricted neighborhood, the numerous trees on my lot h

Gang, I've been watching with interest the beam vs. four-square discussions on this reflector. One thing that hasn't been mentioned has been wire altenatives. Vee beams can be extremely efficient, di

To the forum: I have seen several posts to this column regarding "leaky" coax. After investing a significant amount of time and effort into attempting to understand this phenomenon, I felt my finding
Tyler, Thanks for the input. I agree that leakage can and does exist and can be designed into a cable. I guess the three main points I was trying to make were: 1. A quality grade coax should provide
Bob, Might I add to to LB's suggestion that if youconstruct a trap dipole, use a high quality plenum coax to construct your traps. The silver-braided, teflon-insulated stuff may cost a few bucks a fo
<< > This means that our coax leakage is at least *66 dB* stronger than I submit that this factor is only important in co-frequency situations, where antenna coupling would be much more significant a
