How do I increase the range of my FM transmitter?
In most cases, you use transistors (and/or tubes) to amplify the RF signal from the transmitter. Sometimes, the least expensive way to increase range is to use a bigger antenna, a higher antenna, a more efficient antenna, or a directional antenna.

Urban Environment – Around 1/2 – 1 mile from handheld to handheld, up to 2 miles mobile to handheld, and up to 5 miles or more, base to mobile, with base antenna at 50′.
What is the 70mhz band plan?
The philosophy behind band planning is that it assigns frequencies for certain activities in such a way that all current users can practice the various modes of amateur radio with a minimum of mutual interference. The 70MHz UK band plan is based on the International Amateur Radio Union (IARU) Region 1 band plan.
What is the power limit for 70mhz?
In the UK the 70MHz (4 Metre) band is allocated with Secondary status. It is available on the basis of non-interference to other services inside or outside of the UK. For Full Licensees the power limit is restricted to 160W (22dBW) – lower than normal.
