41. h and an SWR of even 4 to 1 adds very little power loss The only time SWR will indicate a low figura is when the antenna presents a load close to 50 ohms but many mobile antennas will have a base impedance as low as 15 or 20 ohms at their resonant frequency In such cases SWR will indicate 3 or 4 to 1 and yet the system will be radiating efficiently The really important factor in your mobile antenna is that it should be carefully tuned to resonance at the desired frequency The fallacy in using an SWR bridge lies in the fact that it is sometimes possible to reduce the SWR reading by detuning the antenna Field strength may actually be reduced in an effort to bring SWR down Since field strength is the primary goal we recommend a field strength meter for antenna tuning For antenna adjustments the transceiver may be loaded lightly using the TUNE position instead of operating at full power output This will limit tube dissipation during adjustments and will also help to reduce interference on the frequency In any case do not leave the transmitter on for very long at one time Turn it on just long enough to tune and load and get a field strength reading Start out with the antenna whip at about the center of its adjustment range Set the VFO to the desired operating frequency and then adjust the PLATE control for a dip and then the LOAD control Then observe the field strength reading The field strength meter may be set on top of the
