Since picking back up here, Spize said he only programmed 3 out of hundreds. When I had my firsy HR20 installed, I was not told that I had the RF option. As a matter of fact, the installer who was just here last week didn't even know that the HR20 boxes had a RF option. I found out about it here at S* guys and asked D* CSR and they said all the HR20's have the capability for RF whether it has an external antenna or not. All my receivers are set for RF and I'm loving it. No more pushing the button 2 times and pointing it directly at the receiver and wiggling the remote to work. And the Dish Net antennas will work on the D* receivers with the external antenna connection. You only need to make sure the remote is RF capable.
