Antenna Colinear


2 meter Coax Collinear 144Mhz 70cm 430

This is a simple and quick design for a collinear antenna. Covering 144 Mhz - 146 Mhz and 430 Mhz to 440 Mhz. It can produce similar results to a commercial version and be made from scraps of coax. Depending on the mounting location, coax used etc. The 70 CM band may be limited
