ALCON CT 458 SS - remote and base Units can operate by 12V car battery and it is easy to use with Solar panel + 12V battery without any problem. The standard power supply we use 13.5V 16A. Please note that we can also provide adequate solar panel kits, for the remote unit so it can work even where there is no electric power. Due to shipping restrictions and their weight, we do not ship batteries.

ALCON CT 458 SS are designed to operate on a low band VHF/UHF frequency 382 MHZ / 256 MHZ, with automatic multi channel scan for free channel and with high quality voice transmission. The low band frequency will bend with the terrain so optical visibility is not necessary. Signal will travel through hills and valleys, over mountains, even underground into a coal mine. When used over water, the combination of ALCON CT 458 SS- 45W power and the UHF/ VHF frequency translates into a tremendous range. Depending on conditions an over water communication distance of 200+km is possible. Range depend of terrain configuration, and other factors that can weaken the signal such as: urban area with tall buildings, massive mountains and similar

Multiple Channel Access: 20 channels automatic scan to avoid interference
Built-in voice security circuit (Scrambler).
Works on two frequencies in the same time : 382.100 MHz / 256.100 MHz
You should check with local authorities for legality of usage for these frequencies
