This review is from: 75 to 300 Ohm Matching Transformer

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).

1.0 out of 5 stars Too cheap, January 30, 2010

This review is from: 75 to 300 Ohm Matching Transformer

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.
