A Look At My TV Antennas

In San Francisco - 315 feet above sea level


There are three masts with several antennas on our roof. 
This photo shows the main mast with three of the antennas.


The antenna at the very top is the Winegard HD8200U all band antenna.
The rotor is a Yaesu G-450A that has a rotation range of 450 degrees
and is able to withstand the very blustery winds here in San Francisco.
Below the rotor is the Antennas Direct XG91 UHF antenna and below it
is an Antennas Direct SR-15 UHF antenna.


The second mast is at the back of the house and has a UHF Channel Master
4228 combined with an Antennas Direct Clearstream 5 for high VHF.
Mounted nearby is a Dish 1000.2 antenna for satellite TV reception.


The third mast is mounted to the chimney and has two antennas, another UHF
Channel Master 4228 and, below it, the Ability LP345F Log Periodic antenna.


STATION RECEPTION

The Winegard HD8200U covers the entire TV spectrum - low VHF, high VHF and
UHF channels, and has a receiving range of up to 65 miles.  With the rotor it's able
to receive channels in all directions - the 12 stations transmitting from Sutro Tower,
just 3/4 of a mile away to the west, the five stations transmitting from Mount San
Bruno, five miles to the south, and the three full power stations and two low power
stations transmitting from Mt. Allison and Monument Peak, 35 miles away, near
Fremont in the South Bay.  In addition, I receive the low power, low VHF station
transmitting from Mt. Chual, 55 miles to the southeast, the two low power low
VHF stations transmitting from Mt. Tamalpais, 14 miles to the north, and the UHF
station that is located on Sonoma Mountain, 65 miles away to the north in Sonoma
County.  When conditions permit we receive some of the VHF and UHF Sacramento
and Stockton stations transmitting from the Walnut Grove site, 62 miles to the
northeast on the opposite side of the 1000 foot high East Bay hills.

When conditions have been really good this antenna has pulled in two distant stations
from the northeast, KCVU at 157 miles near Paradise, and KNCN at 175 miles trans-
mitting from the hills east of Red Bluff.  We don't have the conditions here
that permit very long distance skip, so 175 miles is the best that I've done.

The Antennas Direct XG91 antenna is locked in at 190 degrees and is excellent for
receiving the two VHF stations transmitting from Sutro Tower and Mt. San Bruno
and all of the UHF stations transmitting from Sutro Tower, Mt San Bruno, and the
South Bay locations.  We have it connected to the over the air receiver of
our Dish Hopper DVR and use it for recording programs from the over the air
channels.  With it locked in we don't worry about missing any recordings.

The small Antennas Direct SR-15 UHF antenna mounted at the bottom of the
main mast, and shown below, is pointed at 200 and used as a back up to the XG91.
It also receives the stations from Sutro Tower and Mt. San Bruno and some of the
South Bay stations.


This is another view of our main mast showing the HD8200U, XG91 and SR-15.


WHY SO MANY ANTENNAS?

Why do I need the other antennas?  The CM4228 and Clearstream 5 combination
(pictured below) are used for the HDTV in the bedroom.  While they don't receive
the distant stations, they do receive the stations transmitting from Sutro Tower
and Mount San Bruno, as well as most of the stations in the North and South Bay.


The CM4228 mounted on the chimney is used to receive the stations from Sutro
Tower and Mt. San Bruno, plus the four UHF stations from the South Bay.  While
it's designed as a UHF antenna, it receives both VHF channels 7 and 11.

The LP345, the all channel log periodic antenna, shown below the CM4228, is pointed
north at 350 degrees for receiving the low VHF and the UHF stations in Marin and
Sonoma Counties.  It doesn't work nearly as well as the the larger 8200U, of
course, but is a good back up for the stations to the north.  It also receives the
stations from Sutro Tower and Mount San Bruno off the side and back of the antenna.



Here is a close up view of the Ability LP345F Log Periodic
antenna, photographed when it was on a different mast.


DISTRIBUTION OF SIGNALS

Each of these antennas are connected to individual distribution amplifiers, then the signals
are fed to switches allowing any one of the antennas to be selected with the simple push
of a button at our three TVs and the HD Home Run and converter box receivers.


Please check out My TV Log, for a list of stations received with these antennas.

Reception for four of these antennas, the HD8200U, XG91, SR-15 and LP345
can be seen by viewing the scans from my HD Home Run receivers.
