No modulation just adjustable frequencies?

I want to do some experiments transmitting single frequencies from
a inexpensive frequency generator(from 5.0 HZ to about 30 MHZ).
this would be in a EMI enclosed space so not to interfere with RF.

Is there a way to connect the output of the signal generators red black wire
to a approximate 200 watt pre antenna amplifier .

Depending on the output specs of the sig gen and the input specs of the amp, you may need an intervening pre-amp.
What antenna covers a 5Hz-30MHz range?
