I've been Googling everywhere and have come up empty, so while this isn't technically a D-STAR specific problem, I have a hard time believing it hasn't come up before (or will again).
I got my hands on a Comet SB-97 tri-bander mobile antenna at a really good price. The trouble is, I have realized, how to get 23cm in there from a separate radio. After sleeping on this, I see 2 options: 1. Use a triplexer from Comet or Diamond. This has the advantage of a single-antenna, clean install. But I can't for the life of me figure out how you feed the VHF and 70cm ports from a single radio: will using a T-adapter screw up the impedance or does that matter since the ports will only pass their own band? And is 55db separation REALLY enough? 2. Go buy a separate antenna: maybe an HV7A or something that does 6m and below as well. The advantage is no worries about a *plexer, but the disadvantages are A. screwed up rad pattern, B. much more RF into the 23cm antenna (which would have my IC-T81A on it until I could afford an ID-1), and C. probably cost more. So I refer to the elmers here; hopefully at least some of you have done this commercially as well. Thanks! Mike N7MSD P.S. Existing radios: ID-800H, IC-91AD, IC-T81A (23cm + 6M); future radio possibilities: ID-1, IC-7000, IC-9600(?!?), Alinco DJ-G7
