Dummy load antenna??

I've got a Maratrac I want to use to test a bunch of lowband pagers. I don't have an antenna for it.....how could I make a dummy load for it? (or where to buy?)

You could buy an MFJ dummy load:

A Maratrac to test pagers? Are you looking to do 'range testing' on them; how far out in the real world they will alert? Or just something for on the bench? If it's just for the bench, there should be no need to transmit with a big 100+ watt Maratrac & then waste it in a dummy load.

You might just come right out of the RF board & bypass the amplifier completely - tho make sure to put the low-pass filter in your bypassed circuit. RF board puts out on the order of a few 10's of dBm, which I expect would be enough to flood a room with enough RF to alert a pager.
