DBS & OTA Signal Combining Help Needed * Update
Today, Yammon and I went out to try to remedy the issues described in the thread and I would like to share what we did.
The main thing learned today was re-cap the heads of the RG6 so there are no issues, as the major issues discussed with the DBS signalwere remedied (so odd transponders are once again working).
However, it appears the issue with the OTA is more severe and has left Yammon and I scratching our heads. To simplify matters, after we raised the antenna, so that the two lower UHF bows were no longer blocked (which saw a bit in the boost of the signal) we ran the line directly from the CM 4228 (and through the CM UHF Booster) into the Samsung T-151 reciever. While the majority of stations were reciving stunning reception (CBC was 10 bars, Fox,NBC,CBS,UPN(CBS),ABC,CTV,SunTV,CBCF were 7/8 bars), we appeared to have issues with both WNED PBS Buffalo (43-1/2/3) and CityTV (53-1). While we would recieve 5-7 bars in reception on WNED (which is strange, as both WNED and WUTV are broadcasting from the same tower on Grand Island and Fox has a lower kW), with severe pixlization. In contrast, CityTV was jumpy with signal strength comming in at 8 bars however continously dropping out. We spent numerous hours trying to peak strictly WNED and CityTV but to no avail.
At this point, it was decided to ignore the situation with WNED and CityTV and move on towards the multiswitch issue. Basically, we are left back to where we started. With the multiswitch enabled, there was only a 1-2 bar drop on stations, with the lowest being 6 bars (SunTV, as we were no longer paying attention to CityTV/WNED). This was acceptable, and as I ran the line directly into the reciever signal quality (as stated above) was strong. However, immediatly upon adding the Diplexer to the setup, SunTV as well as WIVB (4-1/3) dropped out while some stations such as WUTV or CBLT were still at 9 bars. Even with only one line connected to the BMS 58 Multiswitch, we were still experiencing drop outs. Unfortuantly, we didn't have any F-Terminators and only caps, so I can not comment if that will make a difference (may try that if I have time tommorow).
At this junction, we tried a new theory which we thought would work well. We removed the Antenna from the BMS58 and inserted it to a Nextech (Radioshack/Source) 5-2400 GHZ Goldplated 2 way splitter. One output was left empty while the other was connected to the antenna input on a diplexer, with the satellite input connected from the BMS-58 to the diplexer (a technique I was previously using with this same multiswitch to combine Cable/Satellite feed in one room so only one wire would need to be ran) and then diplexed that backout with a satellite and antenna feed. This led to severe loss of signal strength on numerous stations, including only 7 bars on CBC and 4 bars on WGRZ. We had thought that by doing this there would be a significant amount of less dB lost in the line however it appeared there was more.
Unfortuantly, at this point we were both frustrated, stumped and tired, as well as it being the weekend so we had other commitments, so we called it a day. However, I know it has left us both pondering in what direction to go. I want to be able to distribute the DBS signal to up to 8 rooms (well 6 with 2 spares that are not being presently used but already have the line ran), and want to do the same with the OTA-HDTV. Right now, I can physically swap the RG6 from DBS Reciever to OTA Reciever and perfectly recieve both the signals (excluding CityTV and WNED).
The only idea that we could come up with was...
Attempt to find a Terk Diplexer which is made specifically for Terk's.
Attempt to find a Dipelxer with a lower signal loss level
Connect a new OTA reciever in place of the Samsung T-151 (I believe Yammon will bring either his T-451 or LG 4200 next time.
We could go stampeders route and try the home distributor, however that will requrire all the feeds being indoors and I need an outdoor solution.
Obviously, the simple thing I want to get done is remedy the WNED and City TV issue. Does anyone have any insight as to what we could perhaps do? The antenna is picking up both NBC, FOX SunTV (NBC is the most extreme Eastern Station and middle UHF Frequency, Sun TV is the extreme Western as well as the highest UHF Frequency, FOX is the lowest UHF Frequency). I find it interesting that even though SunTV and CFTO broadcast at higher power, they are at lower elevation and while CityTV is at lower power and higher elevation, I can not see it (except for the occasional blip where is whos 7-9 bars (and I was able to pull the station in without dropouts, with my indoor antenna sitting on the roof outside the window)
Once that situation is taken care of, I can move onto the my multiswitch issue, however if the worest case scenario is that I will be required to hardwire the reciever every time I switch between the two, I will live with it.
Any ideas or conversation is greatly appreciated (and if we can perhaps not close this thread, or join this with the closed thread, that would be swell).
