Looking for VHF filter

[Pab Sungenis]

We're moving in the fall, right around the time the S3 comes out. At that time it's bye-bye DirecTV and back to Cable.

I have a nifty new roof antenna still in the box, ready to be installed at the new house. However, the house is already pre-wired for cable, with just one lead going to each room. I'd like to combine the antenna and cable into one feed and "unstack" them, basically, at the sets that have S3's at them.

Since all of our OTA Philadelphia locals are on UHF, it seems obvious to me that all I have to do is slap a VHF filter on the antenna before I feed it into the combiner, so the NTSC VHF feeds from the antenna don't conflict with the cable's own VHF feed for channels 2-13. This gives me best of both worlds as I see it.

Anyone have any leads on where I could find such a filter?

The first thing I'd try is a VHF/UHF splitter connected in reverse.

Sorry, but it's NOT that cut & dried.

Are you ONLY going to get ch 2-13 on cable? Since most cable systems have many dozens MORE channels, it's going to be WAY more than the 12 channels on 2-13. (unless you're only getting "broadcast basic cable", but if you were, why would you even bother with the cable in the first place??? :confused: ) The problem is, as you go higher in the cable TV band, you will start running into conflicts with the UHF TV band you are trying to get off-air. The cable band at channel 65 actually starts coming on top of the UHF band on channel 14, so if you have both cable channels & UHF in that band, you will have problems. Also, you did mention the S3, which I assume you also will be using digital cable - the majority of cable systems place their digital signals above cable ch 78, so if you are knocking that out with your "antenna signals", the S3 ain't gonna work.

most cable systems have many dozens MORE channels, it's going to be WAY more than the 12 channels on 2-13.There are several dozen cable channels below UHF 14, tucked here & there among, below and above the traditional #2-#13 broadcast channels, so it depends on what the cable provider is doing with his channels and how high the user's filter cuts off. Trial & error will quickly show what's happening.

I use a Channel Master 7775 amplifier on my antenna, its UHF only and totally blocks any VHF. (Which is a problem for me now there's a VHF station I can receive.)

Rewire for two coaxes per location, that is your best bet. Mixing cable and antenna will cause loss of channels and signal quality.
Properly upconverting and downconverting will cost you.

I wonder if the Series 3 will allow you to set one tuner for OTA, and the other for cable.

To be honest, I doubt ANY combination of cable with OTA will be possible on the Series 3. (Don't think it's possible with earlier TiVos.) You likely won't be able to set the machine up for that combination of signal sources.

Satellite and OTA, yes, but not cable and OTA. (At least I don't think so.)

I thought the S3 couldn't do anything with Satellite or Cable via a set top box,
as it has no IR blasters or serial control.

Only OTA via coax in and/or cable(analog or digital) via coax in.

Pony said in an interview that you could mix and match cable and OTA.

The Series 3 will not work with satellite.

OTA and cable, yes, because thatis what it is designed to do.
Satellite and OTA or cable, no, as it doesn't have A/V inputs or IR control. It has two input jacks, one for cable RF, the other for OTA RF.
You will be able to tune one of each at a time. It will decide what tuner to use though.

When did fall become - right about the time the S3 comes out ?

The 2nd half of 2006 is all that I've heard. That probably means December 23rd.
