I can grasp the "all band" application of a Log Periodic antenna. Now, explain to me the the theory behind an "all band" phasing system -- one that doesn't use infinite lengths of coax....

Another question (pardon my ignorance) Is it a given that the TOA that the antenna is "putting out" should be the same as the incoming angle? Is their no change over time? Sure is gorgeous, tho' - 73 de Mike KB3EIA - |

An antenna radiates at all elevation angles. It does not "put out" at any single angle. Likewise, it receives signals from all elevation angles, not just a single one. Roy Lewallen, W7EL |

Roy Lewallen, W7EL Roy, You know better than to make the above "Statement". It is way to "General" in nature. Certainlky there are a whole raft of "Antennas" that have both Horozontal and Vertical Beamwidths, that are NOT Omnidirectional. The OP didn't specify the Frequency at which the "antenna" was being used at, and the "Higher" the frequency the more likely the antenna will NOT be OmniDirectional, and will have Horozontal and Vertical Beamwidths....... |
