uhf/vhf mixer for antenna input to tv

[crossd]

..don't know where else to ask this..i'm sure someone here can guide me.

i am still using an old tv antenna with 300 ohm twin wire inputs..works fine..
on my old 1979 Sony..still works!!!..
got a 2001 Sony with only ONE input (coax type)..manual says from antenna must use an EAC-66 uhf/vhf mixer (this is Sony's part #) or equivalent then plug this into tv input..

Problem: no one makes these mixers it seems or at least i can't find anything on the internet..does anyone know how to solve this problem?

Wal-Mart around here sells a package with both 300-75 and 75-300 converters in it for $4.95. Here is Texas/Oklahoma.

In one of my drawers I have an old Zenith dual-300ohm VHF/UHF adapter with a male Fconnector. It came with my grandmother's 83 space command (long gone). It serves its purpose very well.

i tried the radio shack transformer suggested above and i have other 300 to 75 ohm converters..unfortunately they only let in uhf..up to channel 13 i think..when i try above that i get 'no signal' and a gray fuzz..so i need a beefed up transformer that actually mixes the two for input to the tv..i guess i'll hack around some old time tv repair shops..they may have that Sony EAC-66 or your Zenith equivalent laying around..

Just to make things clear, VHF is channels 2-13, UHF is 14-69.

The device you're looking for is not a mixer but a VHF/UHF combiner.
This will have an input for the VHF antenna, an input for the UHF antenna
and a common output for the 75-ohm connector on your TV. If you
get a device that has only a pair of screw terminals and one coaxial
connector, it is a simpte 300-to-75-ohm transformer and is not what
you need.

Assuming you have separate VHF and UHF antenna cables, you do connect
them to the combiner and everything should be fine. On the other hand,
if your antenna is truly VHF/UHF and has a single cable coming down,
it can be assumed that it has a built-in combiner, and you would simply
connect it to the input port of your TV.

Are you sure the antenna you have is designed for both VHF and UHF?
