For REALLY low cost test equipment for use during the developmental stage, refer to Dr. Keenan's book " Digital Design for Interference Specification" Section 6.3. This is something one can build himself, uses a dipole made of 300 ohm TV antenna, an FM radio as the receiver, a signal generator, and a digital Voltmeter. Dr. Keenan's book is published by TKC in florida, (813) 544-2594 is the last phone number that I have for TKC.
