You have a nice looking installation. I hope you tightened those back reflectors well. Both of mine fell off in the high wind and had to be re-installed. Since then everything's been okay.
How have you got your two antennas tied into your system? Are you using switches like I am?
Thanks. I noticed the cheap hardware when I assembled it and made sure the joints were torqued and didn't move.
The Yagi is connected through 20' of RG6 to a Silicondust network tuner in the attic. I will buy a second HDHR-4US tuner and connect the bowtie antenna the same way; no RF combiners, switches, rotor or pre-amp. The lack of a need for antenna pointing and switching makes it easy for a media server computer to DVR shows and stream the antennae. Which tuner provides which channel is configurable, ensuring the appropriate antenna is selected and available to our devices locally and over the internet using Emby media server
and clients. To compare the new XG91 multi-path rejection to the old antenna I would pull out my smartphone and stream KPIX from the back yard when I saw an airliner coming in to land. I'm not that close to the airport, either, indicating the broad beam DB4e is not good for multi-path in the hilly bay area.
I checked the DB4e in it's new orientation towards Mt. Allison. It provides a modest improvement to KGO-TV RF35 VC7.1 repeater in Fremont, which is the only major channel in the SF bay area I am not getting perfectly. The funny thing is the 45 degree off-axis San Francisco XG91 gets all the Fremont stations without issue (at least the ones I am interested in) except
for the weak 12KW KGO repeater. I don't have a VHF antenna to get KGO from Sutro. So this means the Fremont-pointed DB4e antenna will largely exist for the purpose of somewhat improving the reception of KGO RF channel 35 repeater. Probably I should exchange the bowtie for a Yagi aimed at Fremont to get a signal with no dropouts at all, as the DB4e to Fremont still suffers the occasional pixelation.
