Details

GB Antennas GB-4 is a unique four band beam offering 6m,2m,70cms & 23cms.

With many hams turning to 23cm the prolification of antennas on one mast means that everything must be upgraded to take the load. The GB-4 with 4 bands on board means that with one antenna the load can be cut back. It offers useful gain on the four bands 6m, 2m, 70cm and 23cm. Although 4 feeders may seem cumbersome, it is probably the most efficient way of engineering the design. Any 50 Ohm low loss coax cable can be used such as RG-213, but Westflex-103 is recommended for use on 23cm.
