Had swr increase with power on time 3 times. These all occurred with 1.5KW. - BN-86 on a TH7 caused an increase in swr after a few minutes of key down. - A section of hardline had taken a lightning h
I just got one. Tony Lately, every time I post a message to TowerTalk, I get back a couple of "nondelivery" error messages like the following one, relating to <steve@netmakers.com>. Am I the only TT
Why not do like Force 12 recommends for their 40m beam? Haul up the driven element and tune for resonance on 30m with a balun and coax attached. Then attach a balun and coax to the reflector and haul
I am shunt feeding my tower on 160M. I have a C31XR, MAG240N and WARC7 on the mast. After one season I have not arced through the insulators on the boom to elements. I ran full legal power on 160M. D
Hi Pete. I have the coax for the low bands go to the coax switch at the base of the tower. This gives me an easy place to check the coax. For the high band antennas I run either coax or hardline up t
Hi Kirb. As I stated in an earlier email, I like the idea of having the coax wrapped around the mast. This seems to be simpler than a loop of coax hanging down from the boom as a rotor loop, especial
Hi Bob. You have a few choices. Some folks install steps on the mast. With a strong mast this seems to work, like 2" x .25" wall 4130 steel. Some install a second rotor plate between the rotor and th
Any idea on an email address for this person so I can respond to something he listed on towertalk? Couldn't use the normal way of responding as it kicked back. Tnx N2TK, Tony ________________________

I have been using 2 - 4" PVC pipes that were installed before the concrete was poured for the basement walls. All my cables go through these pipes. I use fiberglass insulation to seal them. This make
I just used a short piece (about 5") of #12 wire. Wrapped a few turns of the radial around the center of the piece of wire. Then bent the wire into a U and pushed it into the ground. After a few mont
Hi Eric. If possible I would like to expand on this subject somewhat. Here in NY the corrosiveness of the soil ate through my cadwelded #4 stranded copper wire where it was attached to the copper cla
Recently I got to operate at a station that had 2 tribanders - a Force12 and an A3S. They are at similar heights and typically work in a similar fashion with the edge to the Force 12. This time the A
No water inside any of the traps. The antenna worked fine last time I used it in February. The only thing that was changed on the antenna since the last time I used it was adding tape to the trap cap
Hi Stokley. Did not see any difference in the swr curves with and without tape on the trap caps on the A3S. Seems only the Scotchkote made the difference. N2TK, Tony. Hello TT'ers, I was very interes
I do believe there are 2 Force 12 companies. When I bought several beams as a group buy, there service was great. A few years latter I bought 3 beams for myself. The service, and after delivery suppo
I got tired of trying to use the spark igniter. With some Cadwelds it just didn't get the starter material going. Tried a torch, but unhandy and you have to keep the flame low so you don't blow out t
When I lived in New Jersey I used those bronze ground rod clamps on all my ground rods. The tops of the ground rods were buried about 6". When I was getting ready to move, I pulled up all the coax an
Did M2 ever do anything about the awkward programming of the control box. It just didn't seem simple to change direction when I operated a several year old 2800. This unit made you read the manual on
Interaction was my concern too when selecting a 40M beam since it would be on the same mast as a tribander. I decided on the Force 12 MAG240N since it doesn't have a resonance in any other band. Went
