It seems to me that a minimum charge and a per order handling charge basically address the same problem, which is that it costs the supplier virtually as much to handle a $5 order as one for $100. At
Just one other thing -- this virus, as well as other ones most popular currently, DO NOT get their victims or their fake "From:" addresses from anyone's address book -- instead, they are snagged from
If I understand what I've read correctly, this is a trade-off. If you don't tension to spec, the guy will sag more than it should (because of its weight). Then the tower will move more than it should
That IS what Force 12 claims, I believe, for their N elements, used with THEIR tribander (the C-31XR). Presumably, that is based an actually having tested the two together. I don't think you can reas
I share Dave's interest and concern. I was just reading a sample article on Antennex about a 90cm-long 40m monopole that I found just a little too good to be true, claiming a radiation resistance of
I don't think so. I have noticed this phenomenon with my new-style G-800SA as well. Tentatively, I think it may have to do with imperfect contact in the plugs I use to disconnect for lightning protec
Hmmm... do you have any connectors in the line between the back of the controller and your rotator (other than the factory ones? My suspicion has been that my Cinch-Jones plugs are the source of the
It is, however, important to note that the "A" series control boxes -- the ones that use 6 wires rather than 5 -- are entirely different inside and much simpler. Still no free RS-232 interface though
Hi Peter -- I may not have given them enough credit. Here's what Force 12 claims for the C-3, and I have always found their specifications to be honest: BAND GAIN NET GAIN F/B SWR 14.000-14.350 12.6d
It's my understanding that the numbers are from NEC-2 and NEC-4 modeling, and that those for 10, 15 and 20 are quite consistent with theoretical predictions for yagis with only 2 elements and the rel
quickly I think that the Force12 Low Profile Tower (http://force12inc.com/lpt1a-1.htm) might do the trick without inflicting quite so much financial pain as the ENG jobs. Stock, the winches are hand-
w4zw@comcast.net It would be interesting to look at the various antennas at that QTH in YT or TA -- given the effective height of those antennas, I'd expect them to be too high for some paths (like J
Gave up asking those guys a long time ago <g>. There's a lot of folklore out there, but there's also a very good section in Dave Leeson's book on hilltop locations and their up- and downsides. That's
Good point... it's also worth noting that Sherm has an interest in the new TowerDepot line of self-supporting towers. Because such a report could have competitive significance, this is at least worth
If you don't need continuous frequency coverage I think log periodics are a profligate waste of aluminum. As a working hypothesis, I've read that on any given frequency a well-designed medium-boomlen
But a 10-30 MHz or a 14-30 MHz log on any given band doesn't even approach the performance of a good 3-element monoband yagi. Check out the M2 gain and F/B claims on the Array Solutions web site -- e

Jim, I don't know if you saw my subsequent message, but I have one of these for 80m. It's terrific for that band, but it cannot be compared with a horizontal antenna -- even a dipole -- at 6.25-.750
Actually not... the W9LT/K3LR design (K3LR wrote it up for QST, but I learned about it from W9LT, who thought it up 30+ years ago) uses 4 "lazy-vee" dipoles, with one driven and three used as parasit
What sort of tower is this? The only mil surplus tower I know of that can be moved so readily is the AB-577 (I think that there's also a taller big brother). Something I should have mentioned that ma
