Antenna(s) and (Pre)Amp Recommendation Req

Postby unagi1 on Sun Oct 09, 2011 7:32 pm

Greetings. I live in Fremont, CA approx 23 miles from San Bruno Mountain and 27 miles from Sutro Tower, where collectively the majority of the stations in the SF Bay Area are located. These are appox 9 or 10 degrees apart from me. Additionally, behind me, there are a few stations approx 10 miles away on two other peaks, 3 degrees difference.

I am respectfully requesting a recommendation for an antenna and amp config for my situation. Most of the stations are UHF, with a handful of hi VHF. The more distant channels in the areas of Santa Rosa, Salinas, and Monterey I really dont need to pull in, if they are there great, but I dont care about them.

I guess I may need one antenna pointing towards the two main peaks, and a small one pointing the other direction, but I'll defer to your suggested config.

I have attached the TV Fool link as follows:

Additional Information:
Zip Code: 94536
Single story single family home, residential area, nothing nearby over single story.
Number of TVs: 2, one is a family room 46" Samsung LN-T4661F @ 1080p; the other is a bedroom 20" Vizio @ 720p.
All buildings within a mile are no more than 2 floors.

Thank you very much for the kind assistance.

You have 2 VHF channels, KGO on real channel 7 and KNTV on channel 12: the other stations are all on UHF: the San Jose stations are in almost the opposite direction from the SF stations, and are all on UHF. I believe that you can get everything that you want with a 2-antenna system consisting of an AntennaCraft U4000 UHF antenna aimed at 285 degrees by your compass. The U4000 is unique in that it's rear reflector elements can be folded vertically, allowing the antenna to essentially become bi-directional, which will allow you to see the UHF signals from both SJ and SF without turning the antenna. In order to see ABC and NBC, which are on VHF, I suggest stacking an AntennaCraft Y-5-7-13 on the same mast, separated by at least 3 1/2 vertically. Aim the Y-5-7-13 at 280 degrees, which is between the two transmitters. Combine the 2 antennas signal into one coaxial cable by using a UVSJ ( UHF-VHF Splitter-Joiner ) then run the coax cable into your house, where you would split the cable into two separate runs by using a Channel Master CM3414 2-way distribution amplifier/splitter. Run the two cables from the amplifier to their respective TV sets. Based on the information that you have provided, all of the SJ and SF channels will come in clearly and reliably if you mount the antennas on your roof and follow these instructions. Good Luck!

Thanks so much. Is it correct that the Y-5-7-13 should be mounted above the U4000?

I suggest that you mount the Y-5-7-13 below the U4000 to keep the center of gravity lower.
