Making a 2m/70cm + 1.25m diplexer
"Rob" wrote in message ... A Diplexer filters out the other frequency signal - and con - joins the two antenna's together on one feed line. Or makes believe to the receiver that there is two seperate antenna's, or keeps the rf out of the other side of the transceiver on a dual band transceiver. Why are you posting all this irrelevant crap? When it is not clear to you that there is a big difference in operation between a diplexer and a splitter, why bother? I guess that I did add to the confusion by saying splitter when I should have said either duplexer or diplexer. It is already bad enough that Comet and maybe some other makers of diplexers are calling them duplexers. I use Comet because that is one that I had handy and did check the loss in it with a HP 8924C. It has duplexer on it and meets the specs that are marked on it. I do not have them handy now, but think it was .2 db for one range of frequencies and .3 for the other. I just loosely used splitter instead of saying duplexer/diplexer. And Yes, I know the differance in all of the above. I had a First Classs Radio Telephone license back in 1972 at the age of 22 if that makes any differance. Been an Extra class ham for over 10 years. Repaired the CB radios for several years to about 1976 to pick up some spending money. |
