tion to the 1/4-wave vertical antenna supplied with the
W20R (or the optional WA250 5/8-wave antenna, which
provides up to 3 dB additional RF gain). If the receiver is
to be mounted in a shielded rack mount enclosure or
other area which may interfere with RF wave reception,
the 7.6m (25 ft) coaxial cable (WA280) permits remote
antenna placement, and the WA250 can be attached to a
microphone stand or wall mounted using the optional
bracket (WA260). (NOTE: Remote placement of the
1/4-wave antenna using the WA280 coaxial cable re-
quires a female-to-female PL258-type UHF adapter.)

FUSE 1/2A: This is a 0.5 ampere, 250-volt, 3AG-type,
fast-blow fuse that protects the power supply from ex-
cessive current. It should be replaced only with a fuse of
identical size and value (Littelfuse 312.500 or
equivalent).
