Sigma Excalibur Compact Home Base CB Antenna Home Base Aerial.


The Excalibur is a compact antenna suitable for CB27/81, PR27 GB & 10M Amateur frequencies. With a power handling capacity of 500 Watts, it operates within the frequency range of 26-28 Mhz and has an impedance of 50 Ohms. The antenna boasts a compact design at 0.95 meters in length, with an SWR of 1:1.5 and utilizes an SO-239 (PL-259 Socket) connection.

This antenna is designed for outdoor use and offers a range of 4 to 5 miles under ideal conditions. Even when mounted in a loft space, it can achieve up to 2 miles of coverage. The Excalibur antenna requires no ground plane, features low wind resistance, and is fully weatherproof. It comes with mounting options for a pole bracket or wall bracket, complete with U bolts for installation.

Specific cable lengths are recommended for optimal performance based on the frequency used. For 27 MHz, cable lengths of 8' 10", 17' 9", 27' 6", 40' 0", 58' 0", and 76' 0" are advised. The Excalibur antenna eliminates the need for SWR adjustments, minimizes bleedover, and provides reliable performance for CB and Amateur radio enthusiasts.
