I have a whole bunch of these cloths pin clips for sale on ebay. I got them from a tv shop that I cleaned out 10 years ago. I never use them myself.

First off, in order to clip them onto the antenna screws of thee TV, the screws have to be loose. The loose connection can introduce issues with the signal when the clip wiggles around. I can understand using the clothes pins if you are attaching rabbit ears or are using 300 ohm twinlead, but there are still work-arounds for the twinlead issue, and today most everyone is using 75 ohm coax.

My best practice is to attach a 75 to 300 ohm balun coil to the antenna terminals of the set I am working on. I leave the balun coil on the set permanently. Baluns are cheep. I bought 50 of them on the internet a few years back at a cost of only 50 cents each.

Once you have a balun installed on the set, it's a simple matter to attach a "F" quick connector ( like these http://www.ebay.com/itm/Axis-F822-F-...gAAOSwAuZX5fEu )onto the end of your 75 ohm coax, and then you simply push it on to connect and pull it off to disconnect.

Anyhow, if you need some go find my ebay auction. Price is 2 for 10 bucks Free shipping.

Bob hits right on the head here. The only solution I like better is agile modulators broadcasting pirate OTA within the house, but that requires quite a few sets of rabbit ears. Even then, if your house has electrical noise issues, a run of RG-6Q or RG-11 to each set from a distribution amplifier is probably the better option.

Another thing to keep in mind, cheap baluns can be had for next to nothing, and most of them have pretty massive insertion losses in the VHF range. This can be an advantage when using a modulator without any sort of gain control that's just too darn hot.
