The 75 ohm type use plugs and cables commonly used for TV aerials and Satellite dishes.
The 300 ohm type uses screw clip terminals where you attach a coloured cable.
All shown here: The FM socket with the thread on, uses a Satellite connector plug.

Coaxial FM antenna


Radio Shack has an
adapter catalog number 278-0291. It takes some effort to push the 278-0291
adapter onto the FM UNBL 75 ohm terminal so wait until you have the 278-0291
installed before you connect your 75 ohm coax on to your new adapter.

This will resolve your FM screw on F connector antenna interface issue.


I see others trying to
help suggest using a 300 ohm to 75 ohm transformer match unit, this isn't what is needed. Your receiver antenna input IS a 75
ohm input.

Where can I find an antenna for this unit?


External FM antennas can be had for as little as $7 for the a simple dipole version (looks like a "T") to a highly directional outdoor type for over $150 at your local Radio Shack below:

http://www.radioshack.com/search/index.jsp?kw=fm&f=Taxonomy/RSK/2032189&categoryId=2032189&kwCatId=2032057&fbc=1&filterName=Category&fbn=Taxonomy/Antennas

The simple $7 dipole is a "twin lead" 300 ohm type that many home stereos shipped with because they are inexpensive, take up little room in the box and work surprisingly well for all but the very distant of stations. These antennas are also found for sale in many department and some hardware stores too. Your stereo may not offer twin lead or 300 ohm hook ups (2 terminal screws near the ANT label) but only a 75 ohm connection (like your cable tv connections), in which case, you'll need an inexpensive 300 to 75 (terminal to cable) ohm balun (or matching transformer) like this one below:

http://www.amazon.com/Parts-Express-Push-On-Balun/dp/B0002ZPIOQ

or to go the other way - from 75 to 300 (cable to terminal) ohm balun like this one:

http://www.amazon.com/75-300-Ohm-Matching-Transformer/dp/B0002ZPIOG/ref=pd_bxgy_e_text_c

Screen rolls and jumps


look at the back of your tv and see if you have anything in relations to verticle hold or horizontal hold. it would look like a round piece with a flat to put a flat screwdriver into . this way you can adjust your screen etc.

A Portable TV uasually has a 3.5mm phone jack as the antenna input, if you can't find the proper matching adaptor, try to construct one using a 3.5mm plug & an antenna maching transformer solder each side with short lenght of 75 ohn coaxial cable

Has anyone figured out IF such a digital anntenna exist yet?


You don't need a digital antenna; any indoor UHF/VHF antenna will work. The antenna and the TV both connect to the converter box, not to each other.

A standard rabbit ears (UHF/VHF) antenna with flat wire (300 ohm) connections can be hooked up to the coaxial cable that goes to the Antenna (RF in) jack on the converter box by using a balun (Radio Shack catalog # 15-1297, about $8). If you have an antenna with coaxial cable already attached, you don't need the balun.

To connect the TV to the converter box, you need an adapter that has an F jack on one end and a 1/8" plug on the other (Radio Shack catalog # 278-257, about $5). The 1/8" plug on the adapter goes in the external antenna jack on the TV, and the other end connects to the coaxial cable that goes to the TV (RF out) jack on the converter box.

Yes, you can. I was able to get my Dish Network remote to work with my Naxa 574 TV. Just follow the directions for the remote and you should be able to use it.
