I use a remote tuned Vactrol to adjust the terminating resistance of one of my pennants. It does make a difference. I have a pot by my receiver that I adjust for best F/B for 3.5, 3.8 and 160M. When
I also had trouble trying to get RG6 adapted to a PL259. What I have been using for at least a dozen years are Crimp-on RG6 connectors. I use a hex crimping tool to make sure I have a good connection

Question on anchor shackles. I have anchor shackles that have a screw pin. The screw pin does not go all the way through with a nut on it. It just screws into the shackle. There is a hole in the pin.
What I have used in the past was a piece of 1/8" Dacron rope about 3' long. I inserted it into the end of the element. I folded over part of the rope and pushed the end cap on to hold the rope in pla
Okay, I'll bite. Who makes antennas that won't vibrate in the wind and have failure of the elements without using a rope? N2tK, Tony Why use poorly designed antennas in the first place, ropes in the
Hi Steve. I agree Force 12 design helps. But at WP2Z, all day long you can see the element tips vibrate from even a light updraft at the edge of the steep slope. This is especially apparent with the
Well Jim, you make a statement that you have an answer to our element vibration problems. We have asked you to tell us what you did to solve this. But, you don't seem to want to give specifics. So, y
The local wire rope company told me that when guy cables are bent around an insulator or thimble and clamped that the strength of the cable is reduced by 20%. He also said if you weaved the cable tog
Would there be a recommendation to have one design for the high bands (40-160M) and one for the high bands (10-30M)? If so, how many turns through the core would be recommended for each? Tnx N2TK, To
Looking for plastic straps to tie multiple coax runs to a tower leg. Can't remember where I saw them. Instead of taping coax to the tower leg, you can use a screw-on strap that will snug coax to the
Make sure the cable covering is okay with gasoline - many are not. I put my cables either in plastic pipe or I bury the cables. Where they come out of the ground and are accessible to the critters, I
Question in regard to Common-mode chokes. I use Force 12 B-1 baluns on 10-40M. On 80 and 160M I use 50 of the small beads on RG141. All the Buryflex and hardline is tied together and buried a few inc
I have been using STUFF for several years in my PL-259 connectors that are outside. I use 33+ tape over the connectors. This past fall I had to take apart a few connectors when I changed some antenna
I'm looking for the part number for the center fiberglass insulator on the A3WS 30M add on kit. The standard insulator for the A3WS is part #122096. But with the 30M add on kit you get a much heavier
Maybe someone on Towertalk can help me with this. I'm looking for the schematic of the MFJ 432 voice keyer. I need the REV 1 schematic. I have the REV 2 schematic. I have 2 MFJ432 voice keyers here.
Hi Dan. Was looking for a one sheet of paper way of having the prefix and beam heading. This way, if I don't have a program running or I am doing something else, I have a quick reference. Found it at
I used PolyPhaser stainless steel Uni-kits for grounding to the aluminum shield on Prodelin hardline. I used the TK-2 ground clamp to attach the stainless steel strap to the galvanized tower leg. Sho
Keep a couple of short pieces of light rope attached to your belt. You never know when you will need to tie off something at the top of the tower. I have a ss pulley at the top of the tower with 3/16
