RH770 Antenna for the Icom 705 and the Smiley Triband

Notice how when using the BNC L adapter the SWR on your favorite HT Antennas is over 3 to 1?

The L adapter adds to the length of the antenna throwing its design frequency off the charts. You must use an external mount to avoid the use of the adapter.

Also, the Japanese and MFJ antennas are cut for 430 MHz not 440 Mhz again having a higher SWR for North American repeaters

If you adjust the antenna length of the 770 below the trap then SWR will drop to 1.2 to 1 for 440 Mhz

The Smiley antenna is telescopic and works fantastic on 440 and 146
