Q: 1. What is the typical range with clear line of sight?

A: The Comtek PR-75a AutoSmart-Tuning Wireless Monitor Receiver (72 to 76 MHz) will give you a range of up to around 100-feet in the most ideal conditions.

Q: 2. What are the advantages/disadvantages of using the 216mhz vs 72

A: The 216 MHz system would be great for large coverage areas. With the right antenna they can reach up to about 3,000 ft line-of-sight. You would only be able to have about 3 transmitters in the same area using 216 MHz, though. 72 MHz has a smaller range of about 1,000 ft line-of-sight, but you would be able to have about 7-8 transmitters in the same area. This tends to be the more popular frequency, as well.
