And once a fellow gets a set of 90 MPH calculations for $250 or so, why, o' why should any future sales of the same calculations cost the next fellow the same $250? The non-recurring cost should be m
Thanks to the many who replied here or in the "background". Seems The posting was worthwhile to more than just me. And I apologize for mixing recurring and nonrecurring; I know better. I was thinking
Greetings crowd: Someone a while back queried about the cost of a tower installation. I will be installing a tower at Lake Havasu City in the next year. I estimated my costs as follows. I am seeking
I can say oone thing about that flagpole ground. I wouldn't think about that approach to grounding a flag pole. Doesn't sound like much engineering went into that. I will be placing some ground radia
Greetings Folks, A while back I posted a set of data which would have been easier to read if it had its spreadsheet format preserved instead of condensed in the posting. It was my initial cost estima
Greeting fellow TTalkers, I have an interesting question. Does anyone know what happens to the radiation lobes for a 40 meter yagi when it height above the ground is changed from 69 feet to 79 feet?

And then, there are two discone configurations: One with the radial screen below a skirt of flaring wires forming the cone, and One with the flaring wires spreading downward from a counterpoiselookin
Greetings, I have a question about choices on 160 meters. I expect to have a new home at Lake Havasu City next summer. I will have a 60/70 foot fixed tower topped by a couple of OptiBeams (16-4 and a
So, owise ones; here is my proposed layout for a ground system at my new home in the dry desert at Lake Havasu City AZ. Sorry, I was unable to drop a sketch into a post to TT - - - probably illegal a
Gadzooks! You are right. A peer reviewed document with all the gory details of grounding is certainly in order. Wonder if there is any chance that the ARRL would pay for such a work of art? In the ol
Hello TTers. I have had great responses to previous posts; so here goes with a new one. My new home at Lake Havasu City AZ will have a buried peripheral ground wire to which my SPG will be tied via a
At the risk of sounding really stupid and having never had an antenna that I could point for 40 M (those days changing soon), I will risk stating that perhaps the 40 meter signals you seek are coming
Many many years ago, I was fortunate to have an opportunity to tour BC station XELO in Juarez, Mexico. Interesting visit. We walked through the inside of the transmitter! It was modulated at the 1 KW
The powerful XELO was located on 800 KHz (kcs, in those days). The original owner/engineer was killed when he opened the cage and the 17 KV zapped him in the head. Best I recall, the filament for all
Not counting efficiencies, doesn't a 500 watt iron require a 6 volt source to deliver 83+ Amps? Warren; W5KKW _______________________________________________ See: http://www.mscomputer.com for "Self
In California, I think that the CC&Rs must be provided at closing, and you have to sign a statement that you've received them(among a thousand other signatures).[I've blotted that out of my mind from
Greetings TTalkers, I going to purchase wet stamped drawings for an AN Wireless Tower topped by a pair of OptiBeams. My grounding plan has been discussed by my home designer/architect with the City E
Greetings TTalkers, I just heard from a friend who lives at Lake Havasu City AZ where I will be moving fairly soon. We were having an exchange, and I mentioned the seven (or maybe more) 20 foot radia
My attention has just been drawn to the articles by Ron Block KB2UYT in QST June - August 2002 in which he says that the tower should be at least 25ft from the house to reduce magnetic coupling betwe
