Has anyone tried this antenna on 70 cm? The reason I ask is that I've been using this antenna for a couple months on 2m and now I'm thinking about getting a dual band mobile for short range cross band repeater use. I'm wondering if it's usable on the 3rd harmonic or if I'll have to get a duplexer and another antenna for 70cm if I want to keep the CGT-144 on 2m. Mike kc9doa
