The way I read your comment, is the only competition you have in the pileups is from other SteppIR users and everyone with other antennas will be second tier. Is this what you are saying ? John KK9A
Radiation angle comes from ground reflection and it has nothing to do with the yagi's design. Testing different yagis at the same height in the same location is a fair test. John KK9A <snip> Yeah I d
The interlaced beam suffer from interaction from the elements of other bands. When you are on 15m the 20m directors look a little like a reflector. So, the gain is less for this type of tribander on
Proper guy wire tension will not help your contest score. Yes, they work very well, and I am ordering one, but I need a way to get the tension close.. temporarily. I have to have this done by Friday
No one will be able to answer your question without knowing the load you intend to put on the tower and without doing the engineering work. You definitely can have less than 80% guy anchor radius, ho
I agree that the pier pin lets the guys do the work and it is the best base for large tower. I don't think the pier pin base will do anything to minimize tower twisting. The best way to stop the twis
I guess you are saying that the base will rotate before the tower breaks. I don't think that much torque makes it to the base on a tall tower. Certainly the pier pin base will not prevent your tower
I have read W2PV's yagi antenna design book many times and there is certainly a lot of useful information in it. However, I believe that his yagi designs are not optimum. He used equal spacing betwee
Usually top antennas are more prone to rain static. Were you using lower antennas during these conditions? John KK9A. <snip> In addition I used the all metal T match which was grounded to the boom. I
Actually the F/B of a 15m beam is very effected by a nearby 20m, since the 20m directors look a little like reflectors on 15m. This is can be clearly seen in a model and it has nothing to do with the
You can purchase ss u-bolts at Home Depot and make your own saddles using a hole saw and a block of aluminum. I'm not sure how much money you'll save over the very nice DX Engineering saddles. Or you
I don't think the problem is not knowing that the other reflectors exist. Certainly many of the "regulars" who responded to the out of topic subjects know of the other reflectors and some of them are
You are way too far away from the salt water to have enhanced radiation below the Pseudo Brewster angle. John KK9A Here is my question - Just how close does a vertical have to be to saltwater to see
Yaesu rotators are much quieter. John KK9A I have a neighbor "commenting" (for now) about the noise of the Ham-IV rotator I am using. I have nothing to compare it to. So my question is are Ham-IV rot
Why would worry about lightning grounding to a rotator that is indoors? KK9A You mean oxidize? Unless it's in a vacuum, yes - it'll oxidize. Cheers, Steve K7LXC TOWER TECH ___________________________
I have a Telrex rotator and I also do not have a wiring diagram. I don't recall having any difficulty wiring it up. Doesn't it have a numbered terminal strip on both the control box and rotator where
There is some missing information in your post. Do you have the concrete base installed? If so you can use a pier pin base with your existing concrete pad and the tower will align itself with your an
Judging by all of the RFI posts on this reflector, you are not alone. There is a whole list of good reflectors on http://www.contesting.com . Tnx to everyone who clued me in to the RFI reflector on g
Since the Yaesu rotator connector is around $50, I would use the supplied one. Perhaps you can use the Yaesu cable on the tower and use something larger going from the tower base to the shack. The co
You need to consider how you plan on using this tower. If you are going to side mount rotatable antennas, you need to place the guys so they wont interfere. If you are only using the top of your towe
