McMaster - Carr is a good source for all sorts of hardware. I treat their old catalogue like a bible. Unfortunately, like so many others, I don't think they publish it any more, but you might try. Ot
Hi Eddy - A few years ago I rebuilt an old heavily damaged TH-6DX. I cleaned and "greased" (Penetrox) all of the tubing "joints". Took apart all of the traps and cleaned them and "greased" all of the
P.S. When you reassemble the elements don't forget to keep all of the trap drain holes down. _______________________________________________ _______________________________________________ TowerTalk
I certainly agree with Mike re the BN-86. The PO of the TH-6DX that I rebuilt only used 100 watts so it had been no problem. However, with 1.5 KW it's not long for this world. If you're not one to ge
Rex - Age is just a number. Gene / W2LU This brings up a question for me. I'm 68 and I decited to quit climbing at 55, but then I get pressed into service each field day because I can "screw up" a be
What ever happened to the old - use a little steel wool (I realize a no-no for many), wipe clean - i.e no steel left behincd, Penatrox, wire clamp. I've used this for decades with no problems. All ab
And don't forget a weep hole in the bottom with some screen to keep the buggers out. _______________________________________________ _______________________________________________ TowerTalk mailing
I've found that a fairly easy to transport and erect antenna for portable operation is just a center fed vertical dipole using 450 ohm line and a true (i.e. not just a balun on the feed line) balance
For temporary support for a "smaller" array, why not 3/4 inch plywood, 2x4's, bolts and U-bolts ? Gene / W2LU -- Original Message -- From: "Dick Flanagan" <dick@k7vc.com> To: <Brahmangou@aol.com> Cc:
I use 1/8" clear lexan as spacers for linear loading and for the boom feedline on my 7-60 MHz log periodic. It's been up for about 8 years now with no problems. If you want real engineering/technical
Yeh Eddy, gaining knowledge in the field is sort of like adding radials isn't it. Get all you can, or have the patience for, and then go with it. But don't knock the guys who may have some theoretica
Any comments on packing PL-259''s with silicon grease to help keep water out ? Gene / W2LU _______________________________________________ _______________________________________________ TowerTalk ma
Hi Hector - Just a guess - A shorted 20 meter driven element trap might lengthen the apparent length on 20, therefore lower the 20 meter frequency and shorten the apparent length on 40, therefore rai
I have a Model 2J1M1 105/63 v 60 cy "Selsyn Control Transformer" ( 2" dia.) fitted out with a gear to match the PPM bevel gear. I need a mating sylsen for the station end indicator. Does anyone know
I would guess that with an "H" frame array you would get the increased gain of four yagis with less required turning radius, broader vertical beamwidth, narrower horizontal beamwidth and possibly a s
Billl - Sounds like good solid info. A couple of questions for you: Would you recommend stuffing the tube with the likes of Penetrox before puttig the wire in as an extra to help keep moisture out ?
Hi Alton - I just finished overhauling my standby ppm and replacing the one that was on the tower.I certainly don't claim to be an expert, but got lots of good info from Kurt's site. Since I'm not a
Re mast height. Probably only a little higher than the turning radius of the rotating antenna since you would prefer not ot have the included angle of the inverted less than 90 degrees. My thought wa
