I ordered some hardware from Fastenal's website last August and my order never arrived and they never responded to my emails regarding the order. Finally afer waiting a month, I ordered the hardware
You should convince your friend to join towertalk. You didn't say what kind of rotator that your friend is using. If it uses a pulse for direction indication he may have a problem using a 750 foot ca
I'm not sure that I see the advantage to this, unless both towers are near each other and very far from the shack. If you connect the motors together so that both turn at the same time, you will need
The coax loss and antenna impedance are both frequency dependant. Your question is impossible to answer without knowing what bands you intend to use with this antenna. John KK9A I have a vertical in
I would not use this coax for your application. Any nick or open connection can cause the cable to fill with water. Belden 8267 is more durable as well as many other solid dielectric cables. John KK9
Another book that I found informative and enjoyed is "Yagi Antenna Design" by Dr. James Lawson W2PV (sk). It originally sold for $15 new and I have seen used prices up to $90 for the book. John KK9A
Why are we posting all of this PayPal stuff on TowerTalk, especially after the moderator said that it was inappropriate? http://lists.contesting.com/archives//html/Towertalk/2009-02/msg00203.html Aga
Steve's answer is perfect- "Do what the manufacturer says". Yaesu mast clamps are aluminum and can break if you over tighten them. Using the supplied bolt properly secures the rotator to the mast wit
Depending on what antenna(s) you have on your tower, it may be resonate on 80m, possibly causing some problems on that band. If a vertical 20' from your tower is your only option for 40m and 80m, I w
I built the 54 foot freestanding vertical at P40A out of 6061 aluminum. Some of the material I had laying around and some was purchase. Larger sizes of aluminum tubing are extruded and do not have pr
Since when is 6063 stronger than 6061 aluminum? DXE provides full instructions and what pieces of tubing to use. The bottom 12 ft alternates between 2 and 2 1/4 inch tubing to the 12 ft level. DXE al
Why would the tower interact more with a tribander any more than a monobander? I have used ring rotators on 10m, 15m and 20m with much larger tower than you're using with great results. John KK9A I t
Perhaps someone can also start a TRUE NORTH reflector. This is of course a towers reflector, and there is an antennas reflector, and one for amps, and ones for various radios... maybe someone should
Are you sure that there is pseudo-Brewster enhancement over fresh water? John KK9A There should be less field cancellation at very low angles for a vertical that looks out over fresh water... look up
I have installed a Cushcraft A3 at 30 feet maximum on DX-Peditions using factory settings and the antenna worked fine in the segment that I set it for. I think something is either wrong with your mea
I do not have a mechanical engineering background, however since no one else has answered your post I will give it a try. I believe that 1/3 in the tower and 2/3 above the tower works fine for most m
The DX Engineering vertical is made out of 6063 aluminum, which is much less expensive. John KK9A I just got pricing from Bethlehem Aluminum for a nesting tubular vertical. .125" wall, 6061-T6, in di
I've modeled verticals near salt water in AO and seemed to get accurate results. I'm not familiar with EZNEC, is there a setting for ground conductivity? John KK9A Hi Guys, TT is tremendous- what a w

The company's name was on the original post so it's no secret. You can view their website at: http://dxblaster.com . The company will even allow an on-the-air demo of this antenna. Compare the cage d
