VHF aerial with splitter for digital tv?

[causeway]

Is it a terrible idea to try to use a VHF splitter coming from the masthead VHF aerial to try and pick up digital tv? I'm not in a great reception area (valley) and see these silly little digital aerials for USB stick tuners...

VHF aerial for TV

I would not suggest you buy a splitter. The concept of 25watts of power being directed to the antenna and not into you TV receiver is a bit hopeful. Even if it didn't cook your TV you would lose some signal to the VHF.
However by all means disconnect the VHF antenna cable and try it on the TV. Much depends on the band your TV is using. I think UK DTV is all UHF so antenna will be cut wrong length and if the local TV is vertical or horizontally polarised. (are all the local Tv antenna flat or on edge.) On edge is vertical polarisation which your VHF mast head antenna will favour. of course the mast head antenna will pick up the best being high but then may lose a lot of signal at UHF due to cable losses. All very tricky. Try it but don't be too hopeful. If it does work then I would still suggest a correctly tuned antenna for the cahnnel you want mounted as high as possible on the stern rail; or similar. good luck olewill

Very unlikely to work, as has beem pointed out the aerial is set up for a specific part of the VHF band nd you need UHF, also the cable is 50 ohm and the tv needs 75ohm, and then there are the slitter losses. Try playing around with a proper tv aerial.

I can't imagine needing both the TV and the VHF at the same time, so why not just try putting the aerial lead into the tuner?
Yes, it will be mismatched and the 50ohm cable will not be ideal, but that may be more than offset by the height.

As others have said, a splitter would have to be very carefully specified to be safe with the transmit power of the VHF.

This one works very well - the VHF antennae isn't that bad for the wavelengths in question - the product also matches the impedance so no problem there.
Mounted it for a friend of mine which, naturally, did not want the weight of another antennae in the mast, but the family demanded TV - he's reporting good results (for VHF, FM and TV)..
