NTENNA

Your FT-817

ND

is supplied with a three-section antenna, model YHA-63 which is designed for optimum performance on the 50 MHz, 144 MHz, and 430 MHz. It also works well on the FM broadcast and other VHF bands. This antenna is intended for connection to the front panel’s BNC-type antenna connector.

For HF and/or 50 MHz operation, most hikers carry their own dipole or collapsible vertical antenna, fed by a small-diameter coaxial cable terminated in a type “ M ” (PL-259) plug, and these kinds of antennas may be connected to the rear panel’s antenna connector.

The

YHA-63

should be connected to the top panel’s “

BNC

” connector, using the following guidelines:

For 144/430 MHz operation (only), connect the shorter cap section to the screw post on the top of the main antenna shaft, then screw the assembled

YHA-63

onto the BNC connector, twisting it 1/4 turn clockwise to secure the antenna.

For 50 MHz operation, unscrew the short cap section, and replace it with the long cap section. The long cap section will provide good results on

144/430 MHz, as well, but those owners not using 50 MHz may prefer the shorter total length of the

YHA-63 when using the short cap on 144/430 MHz.

For shortwave listening using a random-length wire antenna for reception only, you may wish to consider connection of the wire between the main YHA-63 shaft and the cap, using a “spade lug” or similar lug on the end of the wire to provide a secure connection between the cap and the rest of the antenna.

Menu #07 (“ ANTENNA ”) allows you to define which connector

(“Front” or “Rear”) is used on a particular band. See page 60 for details.
