View Full Version : What happens if I split my antenna line to 2 tuners?

Hi guys... for the first time in a long time, I have an outdoor antenna, mounted on my chimney. It has standard coax feeding down into the basement, where I have my shack. I've gotten good results so far, but I was wondering what would happen if I put a simple line splitter and hooked up 2 tuners to it at the same time.

I'd do this solely for FM DX, and mainly for E openings. I'd run 2 Onkyo T-450RDS, both fed off that same outdoor antenna, and then run 2 MP3 recorders which I could check at the end of the day for loggings. The Onkyos also both have RDS, so that could aid in IDs.

Is there a downside to splitting that antenna 2 ways for that purpose?

Thanks!

Fred

Supposedly there's a 3db loss of gain through the splitter, I think....but I've been splitting my APS-13 to two tuners for a few years and I don't see any negatives to doing it. I have a tuner upstairs and a tuner downstairs. The splitter is located where the coax enters the house and then gets split to the two tuners. Go for it.

I've been splitting the antenna line to two tuners for a couple of years now, and also don't notice much difference. I'm splitting in the shack however, in part because running another cable down to the basement isn't easy and in part because it seems to me there's no advantage to doing it "up top".

You will have a little splitter loss as noted above. To make up for this, you can always upgrade the coax to a higher quality type if you want to minimize signal loss. The higher the frequency, the more important it is to use quality coax. One inch hardline would probably be overkill though.

I'm using high quality RG-6, and the run is LT 50'. I'd perhaps be concerned about the loss if I were doing weak-signal DX or even meteor scatter, but in this location, there isn't any more of that - translators and IBOC have done away with it. Es is strong enough the vast majority of the time that I can afford that minimal loss. The same is true if there's strong tropo ( and anything less than that probably wouldn't get me much anyway ).

Thanks for the advice, guys... I put the splitter in, and can't see any real difference!
