GB Antennas

* Frequency 144-148MHz, 430-450MHz * Elements 4,5 * Power 500W * Gain 7.5dB * Front-to-back 20dB * Boom length 1.5m * Wind load 155km/u
If you have limited space to mount separate 2m and 70cm antennas then the GB-2 for 2m/70cm is the ideal solution. It utilises 4 elements on 2m and 5 on 70cm, both antennas have a useful gain of 7.5dB and 500W rating on transmit. The GB-2 is end mounted and so can be positioned anywhere on the mast. The overall length is 1.5m (5ft)

GB-3 GB Antennas 6m/2m/70cm 11 el Yagi

Price: £279.95 (Including VAT) Good Stock Level
Quantity:

* Frequency 50-50.5MHz, 144-148MHz, 430-450MHz * Elements 2,4,5 * Power 1000W, 500W, 500W * Gain 4.5, 7.5, 7.5dB * Front-to-back 15, 20, 20dB * Boom length 1.99m * Wind load 155km/u
The GB-3 base antenna offers useful gain on the three bands 50MHz, 144MHz and 432MHz. At last you can have a directive array on a single mast and enjoy DX operation with a modest rotator and an array that does not take up much room. When you consider the cost of a 50MHz array alone, you realise what good value this model offers. Although 3 feeders may seem cumbersome, it is probably the most efficient way of engineering the design. If you really want to use just one feeder then you can purchase one of our triplexers shown elsewhere in this online catalogue.

GB-4 GB Antennas 6m/2m/70cm/23cm 21 el Yagi

Price: £369.95 (Including VAT) Good Stock Level
Quantity:

* Frequency 50-50.5MHz, 144-148MHz, 430-450MHz, 1240-1299MHz * Elements 2,4,5,10 * Power 1000, 500, 500, 500W * Gain 4.5, 7.5, 7.5, 10dBdB * Front-to-back 15, 20, 20, 25dB * Boom length 2.9m * Wind load 155km/u
After the success of the GB-3 it would seem a hard act to follow but now the GB-4 offers a fourth band 23cm. With many amateurs 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.
