Hello and Merry Christmas y'all ! Here in NW TN we have 4-6" of snow on top of 1-2" ice under blue skies and 14 degrees ... uh, Fahrenheit ! It has been MANY years since we have had a white Christmas

Hi Dave: Yes, I have regular LMR-400 on my satellite antennas, and I'm afraid to turn them for fear of cracking the solid center conductors. I'll just stay terrestrial until things warm up. Supposed
Hi all: I use a crossover with two Top Ten switches as per their application notes. No problems so far. http://www.qth.com/topten/apnote4.htm 73, Jamie WB4YDL the cross talk? There are multiple cause

I use an Orion 2800 for my UST TX-472 crankup supporting a F12 Mag 620/340 and 4BA with 10 foot separation. The rotator works great - no problems there. I did finally have to clip off the pigtail con

Yep, that's exactly what was happening with me. When I cranked it down and looked things over, I found that the connector had significant corrosion from water infiltration. Instead of replacing the f

Hi Dwight: I have a similar setup with the tower 150 feet away from SPG, connected by 4" PVC. I use #8 solid copper wire for ground screen at the tower and connect to the SPG (outside the pipe) with

Hi Keith: In my installation (which is above my garage), I have a bus bar (Cu) under the desk. I have more than one radio, but with my main setup, I have found that using the ground point on my high
Hi Tom: I have a UST 72' crankup with similar top-loading. I have coax arms on mine as well. What I did is bolt a 3 foot section of 1" square aluminum channel stock in the groove of the coax arm so t
Pics are on the way Tom. Presently, the radials are the ground screen of the tower itself - 9 60-footers, with ground rods every 16'. Nothing special, but it works. I'll eventually do a more involved
Notice that Swan Island was one of the DX stations worked - he he. Check out the great CQ magazine article on old deleted entities. 73, Jamie WB4YDL Here's one from 1959 QST.... http://www.w8ji.com/g
A great article by Edmun Richmond, W4YO, entitled "Geopolitics and Amateur Radio" appears in the new June 2005 issue of CQ. I just got mine today and read the article, so it was fresh in my mind when
Hi Keith: No, it's not the Mast Company's mast - I'm familiar with those as well. Here's the site - http://www.wonderpole.com/custom_form.html . It's a bit stiffer. I'm just trying to figure an easy,
To Gene and Fred: Thanks for the GREAT ideas. The Prusik knot is a great idea and simple to implement. Fred, the idea of a simple wooden clamp type ring is also excellent. I'll try both out and see w
Gene: To answer your first question - the Wonderpole is designed so you CAN'T pull the nested poles out of each other - I thought of that one too ! 73, Jamie WB4YDL Jamie: A couple of ideas: 1. Can t
Hi Lee: There is a huge amount written on the simple dipole antenna. I would first consult any ARRL Handbook as well as the Antenna Book. One of my all time favorite web sites is that of Dr. L. B. Ce
Hi Richard: I have a UST 572 crank-up tower and I use the stand-off coax arms. I use Polyphaser ground kits to ground the coax cables to the top plate and a fabricated aluminum plate at the base wher
Craig: I like LMR-600 for the long run between your SPG panel and the base of your tower (or wherever you put your antenna switch). Then use BuryFlex with the antenna runs and in close to the rigs. W
Hi Richard: Sounds like you're hard at it ! HI One suggestion for 80M is to also run a shunt on the tower coming off one section lower than your 160M shunt arm. You've already got the ground plane an
Richard: Got some old 213 coax(or similar RG-8) lying around ? Take the jacket off a chosen length of this coax and push up the braid until it simply slides off the dielectric. Use two large solder e
Hi Frank: Ouch ! Seems I hit a nerve there. Now, I have used insulated copper wire on several occasions and things like copper water piping as a common bus on which you could connect copper flashing.
