Go get the Radio Shack control and try that. If it works, send the monoprice control back to them for a refund. It is a hit or miss with them. I got a small form factor HD antenna to do a test on for someone, and found that it was nothing more than just pure garbage. We ended up dissecting it, and found that the antenna was nothing more than two rods about the size of #8 wire.
Even have had issues with some coax jumpers, and a hdmi cable that I have gotten from them. I found on Amazon their branded hdmi cables are just as cheap, but better on the connectors. As for coax jumpers, will most likely just start making my own if it comes down to needing more than a couple every now and then, when doing work for someone.
