[amsat-bb] 70cm preamp -- with 75 ohm CATV coax?

Hello! With all this 70 cm preamp info flying around, I was wondering if I could change the subject for a moment....

I'd like to receive the new Japanese microsat that is transmitting on 437.???

I have a Hamtronics preamp tuned to 435 Mhz with N connectors on it. I'd probably feed power to it separately while it's on the antenna mast.

My question is this: I have some cable TV hardline gathering dust in the basement. What are the cons for using that to run from the antenna/preamp into the shack? (besides finding connectors for it) Anybody know where I can find connectors?

Thanks!
