Reglement Funkgerät REX

The wireless station SE-201 consists of the transceiver itself in a metal cabinet (14 kg) attached to either a battery case CS-79 (for portable use, HT / anode battery BA-39 and LT / heaters battery BA-40) or a vibrator voltage converter case PE-117 (for mobile use onboard a vehicle from a 6 or 12 V car battery).
The transceiver can be operated with a 4 m rod antenna or for onboard use on a vehicle with a 3 m whip antenna; a remote control set allows the transceiver to be controlled over fiel telephone line from a maximum distance of 200 m.
As standard communications range, a distance of 3 - 15 km is stated, that's a bit more then with a standard citizens band radio.
