Comet CF-413B duplexer specs

[oracavon]

The comet CF-413B duplexer specs say 1.3 to 460 MHz low pass and 840 to 1400 MHz high pass. My question is would it be usable slightly outside this frequency range, say up to 470 MHz?

Yes. According to the graph in the manufacturer's spec sheet (see my previous post, above), the attenuation actually starts around 500 MHz.

When they first arrived on the market - I think mine was a Comet brand - it was sold in a thick vinyl bag clearly marked....

Diprexer

yes, Di-pRexer

I have that same model and I have Tram VHF/UHF and a Yagi 700-800mhz going in with no problems.

Thank you sir.

I use my Yagi 700-800mhz into the Comet for Broward Simulcast and Hialeah/Miami 800mhz wit good results.
