I am planning my "small pistol" contesting station that I will build next year. After reading tons of books and articles on antennas, I believe I do want to stack tribanders to cover for the most lik
I have been wondering the same. Is it possible to use commercial traps (or homemade for that matter) to disconnect parts of the antenna that are not needed for the other bands? For example, build a T
Interestingly, nobody has included OptiBeam in the discussion. Their stated gain is higher than F12 and therefore closer to SteppIR. Rudy N2WQ _______________________________________________ ________
Hello, I was wondering what the group thinking is on placing a KT36XA 10' over a 40M4LLDD. Is it OK to have the tribander above the 40m yagi? Is 10' enough separation? The antennas will be at 100' an
All, After many long months of thinking, reading, and exchanging countless emails with other hams, I am about to pull the trigger and order tons of gear. Literally. Naturally, I am a bit nervous, so
No, no WARC, contesting bands only, mostly CW and RTTY. Sent via Cingular Xpress Mail with Blackberry If you are NOT interested in the WARC bands at all, then this will be a killer one tower, 3-anten
Hello, I was wondering if anyone can share or point me to sources of info on proper tower grounding. I am in the process of building a 90' galvanized steel tower and want to make sure it is properly
Hello all, As I am getting closer to having the new tower and antennas go up, questions that I have never considered in the past keep on coming up. One of them is the choice of coax. As the title sug
The specs for KURALON? RECS15 state: "The optimum fiber dosage of PVA-ECC at up to 44 lbs per cubic yard offers the possibility of reduced-steel and even steel-free reinforcement." http://www.nycon.c
Hello, I was wondering if anyone has experience and suggestions for building a rather large foundation (11 x 11 x 5) in a area with high water table. My builder hit water at 34" and while he has some
I have a rather complex situation that certainly can benefit from the collective wisdom and experience of this reflector. My property has a very high water table and as a result my builder and I deci
Looks like first post came out very difficult to read so here it is again. I have a rather complex situation that certainly can benefit from the collective wisdom and experience of this reflector. My
I really appreciate all the feedback my post has generated. I think it will be helpful to add some further background. Under normal circumstances I would not trust a builder, but I have known this gu
Hello all, Looks like I have misplaced the CD that came with my 21st ARRL Antenna Book edition and I was wondering if there is any archive that has the most current version (1.04). I have the 20th ed
Hello all, A friend of mine was able to procure and deliver for me four 40' utility poles. I plan on using them for a 4SQ set up by mounting aluminum tubing to the top and running wires along the si
I was wondering if anyone can help me select the right material for full-size 80m verticals. My questions are as follows: 1) metalsupermarkets.com offers 6061-T6 aluminum, but not T8. Is there a diff
Dave, Your Rohn-25 verticals are indeed impressive, but unfortunately beyond my own capability to build unless I hire a tower crew. Ditto for making my own aluminum tower. You reminded me that the ot
Gerald, Thanks for the comprehensive answer. I didn't realize that 6061-T6 is more expensive than 6063 as I was looking online prices in chunks of 12 and 24'. Just for kicks I prices a 4-Square set o
Jorge, This is a great question that has been on my mind for a while. I was very tempted to try to model it, but never found the time to do so. I also thought that all I care about is the CW/RTTY por
Jorge, Before you give up on the vertical idea and spend your money on building towers, do take a look at http://static.dxengineering.com/global/images/instructions/dxe-7580fsva-1-rev1b.pdf and http
