UHF ANTENNAS
UHF activity is very low in North Antrim, there are 2 repeaters I can hear. The repeater at Ballycastle GB3KK on TX 430.975 MHz / RX 438.575 MHz and 110.9Hz CTCSS Tone and the other repeater is in GB3DX Londonderry ( Derry ) and 433.300 / 434.900 MHz Access 110.9Hz CTCSS located in Londonderry IO65HA. The simplex activity is very low and hardly any use GB3KK or GB3DX I have just built a simple colinear to access both repeaters. I have included a link on the construction of the colinear.
