Excuse me for jumping in here, and really, I'm not trying to pour gasoline on the fire! I'm a new Tech with an Omni D waiting for me to pass my code test; in the meantime I'm reading this list and a
Jack, the Isotron antennas are monoband antennas. What we were discussing here is a multi-band antenna. Perhaps you should tell us more about what your interests / needs are and what your ground spac
Hi Jack, Welcome to the club! My suggestion from many years of experience is to put up a 135 foot dipole as high as possible. Feed it with ladderline and a tuner with a 4:1 balun. It will work all ba
I also agree. A 135 foot dipoe as high as possible (50 feet or more in the center, inverted Vee is fine) fed with open wire or ladder line works very well on 80 to 10 meters. I also suggest using an
While all you guys are patting yourselves on the back on how well these antennas work don't forget about the poor souls, myself included who don't have space for a 135 foot dipole as well as other re
Carl brings up a good point. Although I do not (in general) using an asymmetrical coupler and a balun, if you place the coupler quite some ways away from the house and insert an RF choke (e.g., Radio
I also use the 135 ft Dipole fed with ladder line. It gives me just excellent results. I use other antennas and feedlines as well, and my experience has been that with a proper setup of the entire st
--snip-- Coax and ladderline both have their place in properly designed antenna systems and both have their advantages and disadvantages. I will describe an antenna system that I installed that appr

One doesn't need a lot of space or high supports for a wire antenna. In fact if one desires to use a wire, make it as long as you have space and supports. Feed it in the center with a balanced feed l
I think you should run an EZnec model of your antenna before you put up another one at right angles to it. You may find that a 90-degree offset will simply result in a lot of the main lobes being dup
True for the higher frequencies, not so for the lower frequencies. For the lower frequencies, his thinking (i.e., 90 degree rotation) was spot on. Still Wes, it was excellent food for thought. I migh
That 73 article says nothing more than when a band's open any sort of antenna will work something. Absolutely no mention of az or el radiation patterns. Or the all-important field comparison with a h
While I highly respect Bob's opinion and have learned a lot from him about home-brewing baluns, I feel his recommendation is the second choice I would make (when starting from scratch). If you alread
I don't know if W9INN is even still alive, but that man knows/knew his business. He built for me a special balun and a special antenna configured for what he thought would be "perfect" for my lot wit
In my previously described antenna system I said I was using a 4:1 current. I did this after initially trying out a 1:1 current balun but got much better results when I changed to the 4:1 balun. 73,
You are certainly correct that I won't get a nice figure 8 pattern broadside to my antennas but I am the mercy of Mother Nature and she arranged the tall pines around my QTH (grin) 73, Joe W2KJ _____
a fan dipole will work fine on multuiple bands, is cheep easy to build and can be fed with either coax or ladder line.. a few examples here... tom N6AJR http://www.ku4ay.net/dipole.html http://www.qs
I have had a couple of Isotron antenna and they are basicall a coil and a capicitor at the end of the feed line, they do work, poorly but are about a nickle better than a dummy load. if that is all y
Jack, I second Pat's recommendation below. I've used the "Center Fed Zepp" that Pat recommends in one form or another for many years. You can't beat it for simplicity, low cost, and good operation. I
