Installation Of Accessories; Antenna Installation; Installation Of Fnb-124Li Battery Pack - Yaesu FT-252 Operating Manual

The supplied antenna provides good results over the entire frequency range of the trans-
ceiver. However, for enhanced reception on certain non-Amateur frequencies, you may
wish to connect an antenna designed specifically for that fre-
quency range, as the supplied antenna is necessarily a com-
promise outside the Amateur band, and cannot be expected to
provide high performance at all frequencies.
To install the supplied antenna, hold the bottom end of the an-
tenna, then screw it onto the mating connector on the transceiv-
er until it is snug. Do not over-tighten by use of extreme force.
Notes:
 Never transmit without having an antenna connected.
 When installing the supplied antenna, never hold the upper part of the antenna while
screwing it onto the mating connector on the transceiver.
 If using an external antenna for transmission, ensure that the SWR presented to the
transceiver is 1.5:1 or lower, to avoid excessive feedline loss.
