Hello all; I'm looking at attaching about 40 feet of Rohn 25 or 45 topped with a VHF gain monopole antenna, which is probably about another ten feet tall. I'm planning to attach the tower to the side
On a similar note, this explains to me why there are soooo many, "stupid guy", commercials. You know the ones I'm talking about, where the guy is shown as a complete: bozo, dumbhead, is stupidly arro
All: There has been quite a bit of conversation regarding the use of wire nuts on aluminum wire. While it will probably not be a problem with ham antenna uses, I have seen wire nuts with burned insul
Correct me, if I'm wrong, but doesn't the well casing only run down to the bedrock, the pump being possibly much deeper in the hole? If so, even the connected ground and casing might not be of that g
Actually, since you are running the balun, you could just run a piece of copper flashing, say 1 to 1.5" wide from the coax shield to a ground rod just outside of the entrance of the antenna cable int
That's why ICE and PolyPhaser advise the use of lightning arrestors in the coax line feeding the radio. The DC blocked guys keep the bulk of the strike potential on the antenna side of the device sav
There is another aspect that hasn't been mentioned here regarding handling antenna downfeeders; Being a member of Sky Warn, I've heard about the possibility, no, the probability of a lightning strike
By today's standards, obviously not. :-( Stan _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://li
One thing crossed my mind... my one thing of the day ;-) Since the resistor would be wired in parallel with the clamping device, with the exception of a possible minuscule spike before the device fir
Stan, good to see that you are serious about grounding. However I must point out that by driving that rod into the floor INSIDE your house you risk all sorts of damage. Everything I read requires tha
One thing to bear in mind, gents, is the effect that UV has on HDPE. I have a nice European (looking) low band Ringo style antenna which is shot because the HDPE sleeve which insulates the radiator f
Three small leds in series, would drop about 6 volts. At 20 mA, from a 12 volt DC supply a typical value for the dropping resistor would be about 330 ohms. A small full wave bridge rectifier would be
Question... doesn't the size of the of the mentioned piece (or pieces) of metal play a significant role in its re-radiating? IIRC there is a resonance issue at work here too. Grounding of that metal?
Interesting Gary, that you should mention this phenomenon. It is the reason that shafts connected to devices such as variable capacitors and roller inductors should be made of a nonconducting materia
Been using that Iroda / Solder-it Pro120 for years. You're right, in cold weather it comes up just a tad short for heavy jobs, even with the wide chisel tip, the model 04, IIRC. That big Master Appli
Well, if you're looking for a tool to do the job, and if you have brazing equipment, such can be made from a 3" long piece of 3/4" i.d. pipe and a cheap pair of either slip joint pliers AKA gas plier
John, your understanding that short is better is correct, however, taking a path right through your house is not, never, ever! Consider also that the outside path, if accomplished with bare wire will
Jim, hello; Your question about sharp bends caused me to re-investigate that statement. "http://www.protectiongroup.com/ProtectionTechnologyGroup/media/PTG/WhitePapersandTechnicalNotes/1485-013.pdf?e
Don't know about other's experiences, Bill, using moth balls but I hung (stored) one of the seats from one of our vans up on the garage wall. Actually suspended it from the ceiling on 1/4" nylon rope
Good tip, I'll have to remember that. I seem to remember reading about a Florida based outfit offering pads of foam impregnated with of all things a concoction base on cranberries. They sell it to th
