The C-5200 has two antenna-connectors. On this time this was usual on mobile bi-band radios because small-size duplexer for rf-power up to 50W haven't been available. So for using the C-5200 on a Bi-Band antenna you will need a duplexer vor 145Mc and 435Mc with max. 50W rf-rating and good selection.

Standard C-5200
Heathkit HW-24/Standard C-5200 (mobile)
STANDARD C-5200 was released in the mid 198es. It is a mobile radio. At first sight this radio is pretty unspectacular. But STANDARD-fans know that this radio was a high-class radio in its time. Construction and design are in a robust and high quality. Usability of this radio is very easy. For displaying settings and current frequncies the STANDARD C-5200 uses a real VF-display. Keys have a backlight lighting for better usage in dark areas like midnight-shacks and cars. DTMF and CTCSS have been available as optional units. The C-5200 has two antenna-connectors. On this time this was usual on mobile bi-band radios because small-size duplexer for rf-power up to 50W haven't been available. So for using the C-5200 on a Bi-Band antenna you will need a duplexer vor 145Mc and 435Mc with max. 50W rf-rating and good selection. Maybe you think this is a disadvantage.

How to activate crossband on STANDARD C-5200?" There are two ways activating crossband-mode Way 1: Push key "SP" while pressing key "RMR" 3 times. But then sending will work without modulation-signal. Why this? We don't know. Thanks for info to Simone from Italien Way 2: Switch of your C-5200. Remove, top-cover, bottom-cover and front-panel. On the front-panel please look for jumper 17 and desolder this jumper. Complete your radio again and press key "RPT" during switching your radio on.
