Gary Regarding tower height No big deal between 70ish and 80ish feet... I found that the difference between 20m at 95' vs 35' and or 15m at 95' vs 45' were that higher was sometimes better and then t
For a Mosley retrospective.. Mosley tribanders typically had 1 trap per element. Hygains of the day had 2. The Mosley driven element was insulated from the boom (sitting on a pair of black plastic mo
Paul If that is all you plan to put on it, the Create should be fine. For what it is worth, I had one that lasted about 18 months before the gears were completely trashed. All I had on mine was a 3 e

Does it matter if they all radiate from one or two attachment points/legs at the base of the tower or do they need to be spread out on a ground buss? Would it be okay to have a copper pipe buss aroun
Hello all... Within the next few months, construction begins on my new hilltop QTH. Obviously, I am already planning for the installation of a pair of 45G towers, which for the heights I expect, Rhon
In 1988, In Metuchen, NJ, I lost my variance request, "because I didn't prove that I needed a 70' tower". (Even though I had clearly done so.) Spent well over a kilobuck on attorney's fees staging th
This happened to me too - though in my case it was in 3 sections stored on their sides at ground level... If it was me, I'd bite the bullet and take the whole thing down and then 1) replace the broke

A lot comes down to your primary objectives. The ori9ginal question harked back to tri band contest performance. Somehow WARC got shuffled into the mix. and on and on. Lets face facts... you are not
Dave According to the chart in the ARRL Antenna handbook lengths to avoid for 40M are 58 to 73 feet and 123 to 150 (for ungrounded guys). Also avoid odd 1/4 wave multiples for grounded segments. It g
Compare the difference in gain between the yagi and a dipole. A dipole has a gain of 2.1 dBi, so compared to a yagi with a gain of 8.1 dBi the difference would be 6 dB. 6 dB is a power ratio of 4, so
Denny, Put it up and play!! If you are a good enough operator, the marginal difference between perfect and easy wont be a factor. de Bill K2EK _______________________________________________ ________
First thought would be to buy/borrow a metal detector. This approach only works if you know a bit about your local geology. I tried using a high end metal detector to find the iron stakes marking out
Here is my 2 cents on a long and interesting thread... My original installation was 90' of 25G on a windy hilltop. 20' of 2" schedule 80 mast with 10' in the tower. Antennas 204BA, 4el Cushcraft 15 a
I have been given a 19' Lightning Sail boat. The hull is sound but it will need considerable attention before it is seaworthy. The mast is a tall metal construction A very good friend of mine (WB4CPZ

Probably the most uncomfortable tower experience I ever had was while putting up 90 feet of 25G. I walked up the first 20 feet and guyed that off. Then installed the next 10 feet plus permanent guys.
