On the W1KK system we recently upgraded the 23cm duplexer to be a triplexer. And we've got a new antenna and a couple of hundred feet of 1 5/8 that will be going up as soon as the WX permits.
With decent HAAT 23cm plays quite well ... not much different than 33cm and we have a lot of new 33cm systems that have been deployed here in New England. Bob W1QA
