A fire truck, for instance, could have an antenna mounted on its front, and up to 4 feet over the top of its roof, so we might look at as much as 20 feet of length. I realize this places us over the 3 meter max so one of the ???? is whether LFAM is realistic. Hi Ari, As you have described it, and have seen the discussion in regard to the need for ERP - you are so deep in the debit column with AM power EQUAL to a local broadcaster, that to climb out of that hole would be prohibitive. READ: no fire truck has a power plant sufficient to cover both the antenna system losses AND "overbroadcast" as you desire. And this is for ONE station only. Imagine your broader mandate to "overbroadcast" all local stations and that hole just gets deeper. Am I way off base here, can any antennae, fractal or other, or any AM antennae technology, be utilized to design an antenna and propagate this type of signal? With such a plea, to the savvy it reveals you are in over your head. 73's Richard Clark, KB7QHC |
