3- Screw the fiberglass loading coil and stainless steel whip assembly into one of the 3/8 X 24 connections on the MFJ-347. 4- Repeat the above steps for the other antenna section.
5- Install a VSWR meter at the transceiver and apply 10 to 25 watts of power. 6- Adjust the VSWR meter and output frequency for lowest VSWR reading, indicating resonance. 7- If resonant frequency is higher than desired, loosen the set screws and extend the stainless steel whips until the desired resonant frequency is found. 8- Be sure to adjust both stainless steel whips the same amount.
9- If resonant frequency is too low, loosen the set screws and adjust the whips further into the fiberglass sections. 10- Again, be sure to adjust both whips the same amount.
11- For best results, adjustments should be made in small increments. If required, cut off the bottom of the whips to ensure it does not extend down into the coil.At resonance, the VSWR should be 1.5:1 or less when properly matched. When tuning is complete, tighten the set screws securely. I don't sell used or refurbished equipment.
