p— When adjusting * your: antenna, whether: fixed or mobile, by all means follow the manufactures % instructions. There are same pitfalls 1o be aware of 1 3 SWR meter i nosed remotely: that i & diode 'SWERVE meter, :and ot ‘engineered for VHF applications; readings will invariably. nave errors of 40% ¢r more, Rather than this, use an inline Watt Meter similar to’ the Drake WV, ‘ot Bird Moet 23, with: VHE ‘cartridge: Further, when adjusting 4 mobile antenna.
The :amount ‘of frequency. spread Between any | iwo: receiving o afy two transmitting frequencies: should: nos exceed 12 MHz. Since the receiver and transmitter are independent of each other; vou may have any practical amount ‘of frequency separation you wish here. Only two or more: widely spaced frequencies for ‘the receiver alone; ‘or for the transmitter alone, need be considered under the 2 MHz limitation.
