You can build an attenuator circuit using resistors which is fairly simple and much cheaper. You would need a tiny piece of circuit board and a simple diagram showing what goes where. There is bound to be an example somewhere on the net.
I think someone on this list will know how to build one.

it 217mW to get an EIRP of 500mW.... so with a 1 watt transmitter,
this means 40 metres of RG-58A cable to come in under the legal limit,
and at $1.80/metre... that's $72 worth of cable.
Is there an ever crappier, lossier cable type I could use? Or a
special way to attenuate the signal further?
