Trouble with remote on second TV, not responding from back of house

Hi, Mary with Dish Network Customer Service. The TV2 remote (UHF) can work up to 200 feet from the receiver but can also get interference issues that cause it to not work consistently. One of the things that I recommend is to readdress the remote to the receiver and possible installing a pigtail to the remote antenna on the back of the receiver. I have this on one of my receivers and have never had an issue since. To troubleshoot try these steps:

Step 1: Verify correct Remote being used
Check that the remote matches the TV. Use remote key or sticker on remote to confirm. TV1 is located in the same room as your DISH receiver.
Step 2: Check that UHF Remote Antenna is Secure/Upright
If UHF, check that your UHF remote antenna is securely connected to the "Remote Antenna" port on the back of your receiver and that the antenna is upright.
Step 3: Address Remote
To SAT: Access "System Info" - press and release the "SAT" button then press the RECORD button on remote control. If unable to access System Info using the receiver, use "Video Frozen/Locked Up".
To TV/DVD/AUX: Check for current remote codes and address remote.
Step 4: Check that Remote Control Batteries are Fresh
Check that the you have recently replaced the batteries. If not, install new batteries.
Step 5: Reset Receiver
If the issue is only on ONE receiver, unplug the DISH receiver for 10 seconds and plug back in.
Please note: It may take up to 5 minutes for the reset process to be completed.

If you are still having an issue, to install a pigtail you will need a piece of Coax cable, approx. 3 feet long and a barrel connector. Remove the remote antenna from the back of the receiver, attach the coax cable to the receiver. At the other end of the coax cable insert the barrel connector and add the remote antenna. Then drape the coax cable behind and towards where the TV2 is located. It takes the remote antenna away from where all the electronics are, which are major causes of UHF interference. I hope this helps resolve your issue.
