These were EXTREMELY cheap compared to the $3-$10 each I found around town. I ordered 10 to make several digital antennas (don't buy one at the store when you can build one for $5 that works 10x better). One of the transformers twisted coax connector loose when I connected the wire to it, but it still works. They all work just fine, so I'm happy with them. These are great for hooking up just about any coax output component to a very old TV or as I used them, to build an antenna - check out makezine.tv or just google it. Looks weird, but it works amazingly better than a powered name-brand antenna I purchased from a large department store (to remain nameless, but rhymes with Ball-Cart).

Bought 2 of these 75 to 300 ohm matching transformers. One arrived with a completely rusted terminal connection to one wire. Both units were unusable for me as I needed to screw a connection onto the threaded end. The unit was so cheap that the threads and threaded end were made too small and a threaded coax would not hold. It might work for someone who wanted to use a push-on connector. Too much trouble to return, will throw away.

I got these to build HDTV antennas (technically UHF antennas). There are plans on the internet to use pieces of wire and a transformer like this to build them. they work very well, and the price is negligible.

It does what it is supposed to do and the installation is quick. It is well made and came to me very quickly.

Worth every penny
Well, these bal-uns are what I expected for the price. They are light duty but they work. Not sure how they will hold up outdoors, we'll see. Read more

Build an Antennae
I bought this little guy to build an antennae. Its cheap, seems well built enough, and does the job. I don't regret the purchase.

it works
It works as intended. It allowed me to get only one channel. But I build my own antenna with materials I had at home.

Good product.
It works for my antenna to receive local HDTV signals. I give it a 4 stars since the two wires are very thin.
