Are newer HDHR boxes better?

Post by cnsutter » Mon Sep 23, 2019 12:22 pm

I have an HDHR4-2US that I have had for what seems like ages. It has treated me well, but I have noticed that it isn't as sensitive as my TVs tuner. I can scan channels with my antenna plugged directly into my TV and get like 50 channels and the key ones all come in without any issues very reliably. When I run the antenna to my HDHR I only get more like 35 channels, and a couple of the key ones (Fox and CBS) really struggle to come in reliably.

I am wondering if the newer dual tuner models are more sensitive and are more likely to receive these channels better. I forget when I purchased this HDHR, but it has to be over 5 years ago now. I am assuming the hardware in the newer ones has improved since then but I was hoping someone has some spec sheets or justifiable data showing as such before I decide to upgrade.

Hi,

The gen5 has different demods and improved small signal performance. Generally the performance is similar except for very weak signals where gen5 out performs.

When a TV can easily receive channels that an HDHR can't, the problem is often that the signal is too strong, not too weak. To find out, run hdhomerun_config_gui (located in the HDHomeRun program directory) to check the signal strength of each channel. Use the actual, not virtual channel numbers. If the problem channels show 100% strength, it could be much more than that. If so, try reducing the input signal. If you have some spare splitters you could put one or more in the line until the strength is below 100%. If that works, you could buy an attenuator of the proper value to replace the splitters.

I have a difficult reception issue on RF 12.
SIgnal Quality 60%

Model: HDTC-2US
Device ID: 10519452
Firmware: 20190621

Would a gen5 design offer better experience?

You'd probably see some improvement, though how much is anyone's guess. What kind of antenna are you using? Usually upgrading that would make a bigger difference than upgrading the tuner.

Thank you

I am currently using horizontally stacked AntennaCraft Y10-7-13 pointed at RF 12.
identical length feed lines/baluns to combiner.


I''m exploring options.
Currently searching for better location on roof for VHF antenna array.

OK, so upgrading the antenna isn't realistic, because that's one of the best high VHF antennas ever made (RIP AntennaCraft). KNTV is getting repacked to channel 13 and moving back to the top of the tower on a nondirectional antenna, which will result in about 50' more elevation and a 50% bump in power level in your direction. That alone might be enough to bring it in without any changes. I have a hard time recommending doing anything right now knowing that's on the horizon, along with KGO moving from 7 to 12, especially since you mentioned you're already getting NBC via KSTS's broadcast. Is there some reason you can't just hold off until May 1 to see where the chips fall? Anything you do now is probably going to need to be changed again at that point anyway.

I appreciate your insight.

Going to wait it out and see what happens after repack of hi VHF stations.
