Review on TWAYRDIO 400 470Mhz Connector Transceiver Repeater by Wendell Chapman

Set up was a breeze with the included gamma match. The SWR is under 1.20 over the entire 70cm range. I riveted a shackle to the boom to secure it to the mast with a U-bolt. Please note that the supplied U-bolt does not have a diameter of 30-40 mm as stated. The maximum mast diameter that a U-Bolt can support is 35mm (1.375in, not 1.50in).
