The 300 ohm - twin-lead side allows water to infiltrate into the transformer tubular housing. Not really suitable for outdoor use. I sealed that end with RTV to weatherproof it for rooftop installation. The spade lugs rusted after about a week of exposure. I suggest spraying the terminals with clear enamel after tightening terminal screws.

This item sucked. I inadvertently pulled the 300 ohm wires out of the transformer about 2 minutes after opening the package. I wasn't even rough with it. Poor quality and durability. I can only imagine how well this would've held up attached to my antenna in the storms we have here (60 mph gusts common). Went to a brick and mortar and bought one for a little more that was way better quality and much better durability.

The unit is not really an outdoor unit although it is described as such. The boot does not look as if it would be waterproof and would require some sort of sealent to be used to prevent any corrosion, so be prepared with this before you climb to the top of your mast to install this unit. The other problem is the terminals, these do not look as if they are corrosion proof. I would suggest that you cut the terminals off completely and use the copper wire to terminate on your antenna. Alternatively terminate with some kind of corrosion proof plated terminals. So if you are armed with some waterproof sealant and some corrosion proof terminals this unit may be for you! I have bought three on the units but it is not worth me returning them. The postage for the three units was more than the units were worth in the first place. Unfortunately you cannot buy these units in the UK.

These are good quality baluns. Steren brand products are top quality. These are great for pulling in the new over the air HDTV channels in my area. I bought several so I doubt I will need to buy more, but if I ever run out, I would buy this again.

I bought this transformer to hook up a DVD player to an old TV via coax into an RF modulator. I set it up by connecting one of the ends into the VHF and one into the UHF.

If you are using this application either through a DVD or VCR or even streaming Netflix onto an old TV (which, by the way is possilbe), you only need channel 3 or 4. That being the case, it was better for me to hook up both wires of this adapter to each of the two VHF slots on the back of the TV.

A VHF/UHF hookup will not only work, but you will get pretty good reception. However, with both wires going to VHF, the reception will be absolutely perfect as long as your TV is good. I was thankful for the advice that someone gave me, because it was contrary to some of the stuff I was reading.

As for this particular transformer, it is perfect. I suppose that they are all good. This one is cheap, plus if you have Amazon Prime, you will get free shipping. This is a very cheap and useful connector if you are into older TV's.

Another note: if you are getting interference, it could be something like a cell phone close by.
