What you really want the guy to have is WORKMAN'S COMP insurance. If he gets hurt doing a job on your property you could be liable for his medical expenses and his lost wages. Whether he is a contrac

Hi Roger, Did you find that the fiberglass reinforced concrete had little slivers of fiberglass constantly coming out of it? Also when finishing it was there a problem with the fiberglass? Thanks Gar
By not bonding the rebar you run the risk of an arc inside the foundation with a lightning strike. Part of the strike will go through the bolts that the tower is bolted to in the concrete. Even if yo
Why not just have an adaptor plate made to bolt on to the existing bolts? 73 Gary K4FMX _______________________________________________ _______________________________________________ TowerTalk mail
A grounded tower is NOT less likely to be hit by lightning. Actually a grounded tower is a little more likely to be hit than a non grounded one. However you are still much better off with a grounded
The wind would blow the ionization away before it could build up enough to do any good. Yes you are right about what would happen if the radioactive rod did take a hit! There was quite an uproar her
The overhead HV lines in the UK (132, 275 and 400kV) all have a grounded The overhead grounded conductor is there to intercept or take the hit before the power carrying wires get hit. The overhead c

I am no expert on HF stubs but I can tell you how it is done at UHF. On the 160 receiver you can only use a stub that will provide a high impedance at 160. The line would have to be a shorted 1/4 wav
Unfortunately when you sign up for an insurance policy they have a clause in there where you agree that they can share any and all information with others. Also notice that in Florida it is not Alls
What are the stubs for? What are they tuned to? Why would you have a 1/4 wave phasing line on a single vertical? Or are you saying that the stubs are separated by 1/4 wave on the feed line to the ver
Hi Tom, They should have no effect on antenna performance if they are where I think they are, that is on the feed line coming from your transmitter and not on the phasing line in the vertical network
Sure add more feed line to any poor antenna and it will "look better at the other end". But that doesn't mean the antenna is working properly. The proper place to measure is at the antenna. 73 Gary K
3 S units better would seem an unrealistic number even compared to a poor dipole. How many db difference have you measured? 73 Gary K4FMX _______________________________________________ ____________
The trick in assembling N connectors is to make sure you have the shield wires laid out flat with none overlapping one another. Use a pick to separate them. Then cut the shield wires to the proper le
Why would you think that the end would blow out before the side would? 73 Gary K4FMX _______________________________________________ _______________________________________________ TowerTalk mailing
The tank should be grounded to the lightning ground system. You don't want any chance of an arc between the tank and the tower / ground system. 73 Gary K4FMX ________________________________________
I did a little research on the subject. It seems that the point of explosion will be where the tank gets the hottest and weakens the steel. That point will usually be at the top of the tank where the
You will never get an RF ground that far away. Why do you think you need one anyway? 73 Gary K4FMX _______________________________________________ _______________________________________________ Towe
