Hi all, I realized that I should have posted this query in this forum; apologies for duplication. I've got a 25-year-old 2m Larsen whip on a trunk lip NMO mount (one of the ones with the two screws that bite into the underside of the trunk lid to make a ground connections). Now I've gone dual band and am looking for a suitable antenna. I was planning on buying the Larsen NMO2-70B (35" or so), which would fit right on that NMO mount. But the folks at Larsen advised me against that, saying that, with a dual band, I'd be cutting my counterpoise in half and bring my gain down towards zero, especially on 440. The ideal would be to take the dive and drill the two holes in the roof or trunk, but that's not going to happen for the sake of keeping the peace with the car's other driver. Short of that, they said I could try a mag mount, which would be another $50-60 on top of the $70 for the antenna with coil. The folks at multiple HROs said hogwash as to the grounding issue with the lip mount and said to just put a Diamond DMN-NR770HBNMO on my Larsen NMO mount. Another store recommended the Comet CMA-SBB-5NMO. None of the stores I contacted recommended the Larsen, which surprised me, since I've had good luck with my monobander. In any case, I want the best bang for what few bucks I have. For that reason, I'd prefer to stay with the NMO lip mount I already own. But if it's really going to suck the gain out of whatever dualband antenna I put on it, then I guess I gotta go magmount. And in either case, with dualband antenna should I go with? All help recommendations comments thoughts quips etc. are appreciated in advance!! 73!
