UGGGGH! Why re-invent the wheel? This is a 20 year old, PROVEN, antenna. Plenty of articles tell you how to solve the problems you guys are asking about now. Why not just follow them? Go to Leeson's
Just to be sure everyone has heard this - Scotch Super 88 is MUCH better for Ham use than 33+. Super 88 is the top of the line. It sticks better, longer, etc, in the sun, etc. I know we've posted thi
Hi Pat, Well, to reduce cost, I once bought two boxes (10 rolls each) of 33+, having use Super 88 previously, but not knowing any better. (BTW, this was when I was in the middle of installing my stat
TT's, Let me correct a statement I made a week ago. I was wrong when I stated that galvanizing will lower the tensile strength of the steel. I was using a "rule-of-thumb" that I have now determined t
Joe, dBd is "gain over a dipole". "Real gain", as you call it, has no meaning. Each person defines "real gain" in their own terms. For horizontal antennas, you would ADD approximately 7 - 7.5 dB to t
That's right Tom. Since, from the original question, I deduced that the questioner was not that sophisticated, I referred him to the Force12 antenna spec URL which goes into much detail on this. Thos
Karl, I have a Force12 EF-180C that was an early model that I made several mods to. It's 85 feet tip-to-tip and has linear loading. Since then, Force12 has incorporated most of the mods I suggested i
In case you haven't looked at it yet, click the "Lightning Protection" section of my Website and see what I did. It's right on target with this discussion and includes plenty of diagrams and photos:
Pete, You are not "all wet". You just lack the experience in putting one of these "monsters" up. Here's the situation: An 80M Yagi (of any element count) has elements TWICE as long as a full-size 40M
Right you are Pete. The East Coast WX was the stimulus that caused the design changes. Bill Bill, if you take a hard look at my message, I was never talking about full-size 80m yagis. I agree, those
You hit the answer, Tom -- Space. I have no space for more than what I have up now. My linear loaded F12 rotatable dipole @ 149 feet beats almost everyone in the contest pileups to anywhere in the wo
Of course it's the height. But, the dipole has improved F/S up there too. It's also rotatable!! That's the best part! Bill, N3RR Well, Tom's right, of course, if you only need to work in one directio
I recommend EZNEC V3.0 available from W7EL. Bill, N3RR Request info on obtaining Antenna Modeling software regarding stacked yagis (2 possibly 3) for 10 meters. Looking for software that is very user
Steve, What are you putting up, a 1000 foot tower!!! Why do you need anything larger than 3/8 inch Polygon rod? That's got a tensile strength greater than 5/16 in steel E.H.S. Check out my website: w
I use NEMA Type 4 Hoffman steel enclosures. See: http://www.hoffmanonline.com/ Their catalog is online at this URL http://www.hoffmanonline.com/Product_Info/ and http://www.hoffmanonline.com/PDFCatal
Jim, You will see from my installation http://users.erols.com/n3rr/photos/grounding_pictorial.jpg that I had the same issue where my Single Point Ground (SPG) entry point into the house was some 40 f
Hank, You asked four questions: 1. EZNEC works fine. You need to be an experienced Windows, PC and software user to use it. I have modeled all of my antennas/stacks/towers etc. It is able to show the
Norm's Rotor Service is excellent. http://www.rotorservice.com/ 5263 Agro Drive Frederick, Maryland 21703 (301) 874-5885 Bill, N3RR (Not affiliated with Norm's Rotor Service) I need to get my T2X ser
Let me just say that anyone considering a stack of long boom (or other length boom) Yagis should define his/her requirements first, then model the antennas and the stack and then, iterate the model t
John, Usually, there are local building codes that do not allow A/C power in the same conduit with other cables, especially if it is hard-wired to your electrical panel and especially outdoors. Also,
