Connect Quatro missing 53 channels with same antenna

Post by iissmart »

I have three tuners connected to the same antenna: a Connect (HDHR4-2US), Extend (HDTC-2US), and Connect Quatro (HDHR5-4US). I just did firmware updates on all three, which put them all on the 20250623 firmware. They are all connected to the same antenna with a 1-to-3 splitter. When I do channel scans on all three, the Connect and Extend discover 104 channels, while the Connect Quatro only discovers 51. Notably, it is missing FOX, channel 9.1 in my area. I've tried rerunning the channel scan multiple times at different points throughout the day, but it doesn't seem to find these channels. Is this something caused by the new firmware?

A regular 3 way or a balanced 3 way splitter?

It sounds to me that you may be using a regular 3 way and are overpowering the quatro.

It is balanced. Each output is -5.5dB. It is a BDS103HB splitter if that helps.

I have been running with this setup for many years and am usually able to get all three tuners to sync up with the same set of channels. Sometimes they might be off by a few, but I've never seen this many missing channels before.

Have you swapped the coax cable between the CONNECT Quatro and one of the other devices just to rule out a splitter or cable issue?

I swapped one end of the cable and the issue followed the cable. Replaced it with a different one and tightened all the F connectors, and I'm back up to 104 channels on all three HDHomeruns. Thanks for the help!
