5.5 ANTENNA INPUT
The connector is 50 ohm unbalance and accepts a male UHF type (PL-259) coaxial connector.
An integral lightning arrestor is included in this part and the gas tube is replaceable in the
event of a strike.
5.6 EXT SPEAKER
This accepts a ¼" standard phone plug. When used, the front speaker is disconnected and the
level is controlled by the speaker VOLUME control on the front panel.
5.7 GROUND LUG
The #10-24 lug is used for bonding the receiver chassis to an earth ground. This should be a
low-impedance connection using a large conductor with as short a length as is practical. The
ground conductor is normally a #8 or larger flat braid. Note that this conductor may be a path
of least resistance in the event of a lightning strike to the antenna or AC power lines. Check
with local codes for compliance.
5.8 SPARE
Reserved for options.
