Bandwidth 

Some antennas may need tuning by adjusting the length of an element or 
by other means in order to cover the entire band of interest, please refer to 
antenna manufacturers instructions for details. 

Duplex operation 

When checking antennas to be used for duplex operation, make sure the 
antenna SWR is adjusted for the lowest possible SWR in both receive and 
transmit band. 

General hints 

Always refer to antenna manufacturers specification! Antennas may have 
more than one resonance frequency! A very narrow resonance frequency 
may indicate resonance of cable instead of antenna resonance (Cable bro-
ken or shorted)! 

Keep connectors clean and tight! 

Calibration 

We recommend the "SWR True" to be recalibrated once every 24 month. 
On the "Welcome Menu" the “Calibration Due” will appear when the calibra-
tion period is exhausted. The calibration message will not affect the func-
tions and measurement of the SWR True.
