Tuning your FM Antenna
DAGCO Electronics has done its best to simplify this unit to be tuned as easy as possible. Improper tuning MAY DAMAGE your
transmitter and will void warranty. FM radio transmission is a very tedious task! Please note that RF Engineers have designed and
have been contacted to clarify this issue as best as possible! See diagrams below and simply adjust the radials to the desired
frequency lengths: Please note that all measurements are from the base of the antenna (see below pictures), not from the connector
(to verify you are measuring correctly, the length of a fully extended antenna is 33 inches).
