[QUOTE="a33, post: 1081878, member: 332642"] Plain T-piece creates a risk of impedance mismatch, and some frequencies "disappearing" or having difficulty to lock. But that is just a risk, that you might not notice at all. I've used a selfmade T-piece for some time in the old days (in a different setup!), and didn't notice anything bad. ^_^ The thing to prevent, though, is that with two or more receivers powered on, the voltage of one receiver can reach the other. Risk of a blown transistor in/near your tuner, and maybe more. Splitters with diodes usually give loss on signal level, not on signal quality. It's the signal quality that counts, as long as signal level is above threshold level. So I'm not happy using T-pieces anymore. greetz, A33 [/QUOTE]
