hi
I was just wondering about how 3 antenna 'types' would compare, I can of course pull the spec's off the manuf home pages, but wonder what a real world interpratation would be and hope somone here might have either used them or have some simular experience to share a multiband log peridic and traditional multiband beam(w/or w/o traps) and a optibeam ofcourse there are pro's and con's of each but just wondering what type might be 'mostly best' overall if you tried to just the playing field as level as possible didn't want this to be about cost per say, just overall performance, but having said that, there sure is a big price swing on those types and I wonder , if anyone one of those antenna types have a overall tremendious benifit based soley on improving received signal strength to warrent one getting it vs say another and or a cheeper one tnx |

A log periodic antenna will outperform a smaller trap multiband two element beam, but probably not a larger one, i.e. one with longer boom and many elements. You will be as well to abide with the manufacturer's specifications until you can pick out the specific antennas to compare. A multiband yagi with traps can out perform a trapless multiband yagi, by being longer and using more elements. I don't know if there is a level playing field unless you can be more specific. Well known amateur radio antenna manufacturers who have been around a while aren't likely to try to fudge the numbers as too many hams are quick to model the antennas and respond with not so kind words faster than the marketing department can spread their lies. I would trust them for the sake of picking the antennas and then ask around about how they compare. I would be more wary of satisfied/dissatisfied users information than manufacturers specs these days. Anyone can get lucky and because of that love the antenna. For example, I have communicated three times to Japan from Georgia. All three events were mobile. However, during that same time, I had a tri-band beam up 50 feet and have never been able to make a japanese contact with it. Therefore, one might conclude that my mobile antenna outperforms my yagi. Of course it was propagation and timing. I used a wonderful trap dipole for about three months. It worked fantastically well. Then I put a fan-style dipole up to test it. It outperformed the trap dipole by a great deal. Until I compared it, the trap was great, now it isn't such a great antenna any more. This is what you are up against. Good luck. -- 73 for now Buck N4PGW |

Good luck. thanks for the responce buck, I can' make perhaps 2 comments 1. for testing pourposes naturally I would only compare antennas of 'simular' size etc etc as much as apples to apples as possible in other areas i should have mentioned that. Well aware that a smaller antenna typically wouldn't do as well as a much larger in the test world ...or even real world 2. as far as trusting the spec's I do, and mention that, but i wasn't trying to prove or disprove the manuf spec's simply wondering that if you had all 3 antennas mounted such that they didn't interfere w/each other and were close enough not to matter for the test and you had a 3 way switch and you averaged the results which antenna if any would show an overwelming ''win' tnx again |
