Correct me if I'm wrong... but would it not be better to run some pre-amplification ahead of the splitter rather than try to make up something that has already disappeared? Much the same in say VHF work where it is better to run a receive pre-amp right at the antenna versus running it at the receiver end of the coax? I'd never consider using a passive splitter here, and I rarely if ever engage the pre-amps on the receivers... no need. dxAce Michigan USA ------------------------------ The results might surprise you. When I received my zfsc-2-1 I expected the addional ~3.5dB loss to be an issue. But after much testing I found that it didn't make that much difference. For the most part any signal I could receive without the addtional loss was still present with the loss. I used a HP step atenuator to check this before going to the trouble of mounting the zfsc. I really expected to need a good low noise, high intercept, preamp before the splitter. If you have a "good enough" antenna the additional loss is of slight concern. Since I have all of my antennas, receivers, RF filters on a patch panel, it allows me to easily move the splitter out of line. I use BNC connectors because I was given a "boat load" of them and find them easier and faster to move then PL/SO-259 connectors. A friend wanted a similar setup and I gave him enough bulkhead mount "F" femalefemale to allow him to bring all of his antenas and both receivers to a panel. He found an "old" TV spliter that works very well to below the MW/BCB band. I bought a bag of over 500 for $1 at the local Goodwill store. Another advantage of a RF patch panel is I can connect my Pro2004 IF out to my R2000 so I can listen to SSB VHF/UFF comms. I do have to be very carefull to insure that I don't connect my ham gear to my receiver inputs. At them moment I have them feeding different RF patch panels and simply don't ever connect my ham gear to a receive antenna. I am considering switching all of my receive RF connectors to "F", at least at the patch panel. I have thought of using TNC but they are expensive and are easier to crossthread then "F". Terry |
