    JTBM270 UHF/VHF DUAL BAND BEAM YAGI ANTENNA

    Posted by Rick on Oct 7th 2021

    PROS: easy to assemble, all elements marked. NANO VNA was used to adjust gamma match no problem VSWR good. CONS: notice the mounting U bolt is in front of the VHF reflector which means if you mount vertical you need a non conductive mast.
