WISCO international (Sinclair- Antennas/ SC320 / SC329HD)

SC320

The SC320 is a wideband, high gain, omnidirectional antenna of rugged construction. A stub projecting through the top and the antenna feed point are maintained at DC ground potential for lightning protection.
Severe weather conditions have been fully considered in its construction. It can be installed with confidence wherever wind, ice and snow will be a problem, the SC320 features an extra long support pipe for ease of mounting, using the rugged clamps supplied.

SC329HD

The SC329HD is a broadband, omnidirectional antenna housed in a heavy duty radome. It offers 6.2 dB gain across the full 450-470 MHz frequency range.
The antenna is at DC ground potential for lightning protection.
