Hi Paul, And still, no one would notice. In fact, I gave the loss 100 Xs copper, lowered the frequency to 1MHz and saw roughly 6dB loss - the "standard" S-Unit, against which propagation variations would toss that around to wider variation. I suppose it wouldn't do for EME, but I don't know any work at 1MHz for EME. Still, and all, this determination is easily within the scope of the free distribution of EZNEC which allows any user to make an informed decision about a choice being OK. 73's Richard Clark, KB7QHC |
