Your Transmitter
Tuners, Antenna Switches, Power and Monitoring
22
• Antenna Tuners – use sparingly
• They have loss and are generally not needed if SWR is ≤ 1.5:1
• Most built-in tuners will handle a 2:1 mismatch
• If you must tune up on the air, do it at low power and off the operating
frequency of others
• If you rig has automatic antenna switching, configure it to put you on your best
antenna for each band
• Your station should be configured to monitor output power and SWR at all times
while Transmitting
• Key an eye on temperature meter if you are operating in digital modes for long
periods and/or at high duty cycles
