Alex Funny you bring up the loop antenna. Thats definitely one of the answers I ran across. Though I was trying to avoid the wire loop. But that said actually what I need to drive can be quite a small loop so maybe the right answer. Along those lines I need to look at the driving Z. Sort of

by making a loop around the territory, on which you would like to receive the signal, inside of that loop you will have a very decent reception without using to high transmit power  a 100' x 200' area could be covered with 100mW,  since the wave length of the used low frequencies is multiple

Paul, You really don't want to be building an antenna that radiates energy, which is a far-field concept. In your case, at 30 ft range, you're so far inside the near field that all the antenna articles in the world won't help, since they address radiating into the far field. That's what WWVB

Working on the wwvb simulator and it works really well. On to the last piece. Transmission over maybe 30 ft. Ever notice everyone that makes a simulator has the clock on top? Well thats because its pretty hard to get a 60 KHz signal actually out. Even though I know loopsticks are not great
