Can you split the one line coming off the antenna to feed both OTA into D* box and run other line to FM antenna input on a reciever???

If so what do you use to do this.

The 4228 is a UHF antenna, for TV channels 14 and above. The 4228 is also very directional. The FM band lives between TV channels 6 & 7. It might work for some FM stations but I'm guessing you will be less than thrilled with the results, especially if the FM transmitters are not in the same general direction as TV.

I'm in a bad location for FM and TV, and use a 4228 mounted about 5 feet higher on the same mast as an omni-directional FM antenna, with mostly good results. From my reading here it's important to maintain as much seperation between the two antennas as possible.

The easiest way would be to just use a splitter. You would get all signals at both outputs. I don't know what sort of FM reception you would get from the CM4228 since it's a UHF antenna and is completely the wrong sort of design for FM (band II VHF) but who knows, you can get FM radio with almost anything, I guess you can just try it, a splitter is only a couple of dollars...

please don't attempt to use the 4228 for FM reception, it just will not work well since the active elements are cut for UHF frequecies, not low band VHF. The difference in element lengths can be in "feet". Splitting your coax feedline from the 4228 will also reduce the overall signal available to the TV set. It is just not worth the effort.

A simple FM turnstile style antenna ($20 - $30) with a separate feedline will give you much better service and reception.

Thanks all. I'll go the separate route.

Oh as to OTA Patrickjherbert post above says TV channels 14 and above. The CM seems to work fine on my Boston locals 2, 4, 5, and 7. Is that unusual???

those channels are mapped channels to your receiver that actually transmit on uhf

I should have said "optimized" for 14 and above. I get some of the 2-13 as well, and would probably get some FM, but the omni FM works much better

haha, I just tried this, surprisingly, it actually works pretty well. I got some stations from all over the place, but only the opposite direction of the antenna to about 50 miles, one is about 80 miles away. Where it was pointed I got a few Montreal stations, which is 140 miles away. It works a heck of a lot better then that little "thing," I won't even call it an antenna that came with my receiver.

Did the split affect the level of OTA signal (video)? What is the splitter you are using?

I didn't split it, just moved the antenna input from the TV to the radio, both are very easy to access and I figured that I'd never use both at the same time, so why trouble with the signal loss

Nice find! Thanks :)
