I've have owned a number of DX Engineering antennas and I had good results with most of them. The 20m models are built fairly rugged, using a 3 inch diameter boom and elements starting at 1 inch diam
Actually putting together a good DX station is a little more complicated then selecting a good antenna. The antenna needs to be at the proper height for the optimum angle of radiation. This height va
I disagree, I don't think installing the Yaesu connectors is much of a problem. I agee that it would be difficult to reuse the white connector that goes to the control box, however these connectors a
I had a 160' tower with 5 TIC rings. For 160m I used a 1/4 wl wire vertical hung from one of the guy wires. It worked well and I avoided any RF problems to the rotators which can occur with shunt fee
The Vertex parts department is easy to reach by phone - 714-827-7600 I think you are looking for the following parts. plug - P1091056 pins - S8101130 John KK9A Did we have a difinitive partnumber for
I have modeled this scenario and if I remember correctly, the dipole has a slightly lower radiation angle which should be better for long haul DX. It is also much easier to install since you don't ne
If you want a 60' self supporting tower, you should buy one and not use Rohn 65G. A 60' unguyed Rohn 65G is not very strong and it's somewhat shaky to climb Having to attach guy wires every time ther
Well I guess the term shaky is my opinion based on experience with this tower. As K4XS said we all have our own pucker factor and climbing it with no wind is probably safe. My point was that this tow
OK you're correct. My catalog says the following: The Rohn 65G is designed to provide excellent rigidity and strength in application up to 500 feet when guyed and up to 80 feet when self supporting.
This looks correct to me. You'll have to adjust the hairpin and DE length to obtain a low SWR. GL John KK9A I have been attempting to model an insulated driven element (DE) for a 5el Yagi using YO, a
Tower top plates and rotator plates are not manufactured very precisely and trying to line up two bearings plus your rotator bearing could be difficult. If it's not lined up exactly it will cause som
If you install a 20m monobander six feet below the 40m beam there will be little interaction. If you put a 15m monobander six feet below there will be a lot of interaction. John KK9A What antenna con
Remember that beamwidth is definded as the points where the signal drops 3dB's from the main lobe. After this point the signal does not drop to zero. In many cases the signal strength of a large yagi

With the hurricanes in Florida, you should also reconsider using a set of guys on your proposed 60' Rohn 65G freestanding tower installation. <snip> A friend of mine on the west coast had a NOS 20M B
It's not surprising that you notice some F/B degradation. If F/B ratio is important to you, you can minimize the degradation by increasing your spacing distance. Do you have AO? If so, you can optimi
I was just reading the 3830 results from last weekend's contest and I saw an interesting comment by 6Y1V / KY1V. http://lists.contesting.com/archives//html/3830/2007-03/msg00551.html The 6Y1V station
I think the phasing difference in using different antennas comes from the driven element not being in the same vertical location. You can adjust for it by adding more coax to one antenna, however cal
I used Phillystran on all of my towers with great sucess and ease of installation. I don't understand Phil's post. I wouldn't use anything but Phillystran. In addition to the strength, I think it loo
You didn't say what model or style TIC Ring you have. I have never had this problem with the older units that used the Bison motor or the next version that used the German motor in the aluminum housi
