Your
FT-818
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 ver-
tical 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 follow-
ing 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 ran-
dom-length wire antenna for recep-
tion 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 58 for
details.
