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
gives you a view from street level showing two of the masts.


The antenna at the very top is the Antennas Direct XG91 UHF antenna
and below it 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 Antennacraft Y-10-7-13 yagi for high VHF, and at the
bottom of the mast 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 low VHF, high VHF and the 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 one low power
station, transmitting from Mt. Allison and Monument Peak, 35 miles away, near
Fremont in the South Bay.  In addition, we receive the two low VHF stations
transmitting from Mt. Tamalpais and the three UHF stations that are located
30, 45 and 65 miles away to the north in Marin and Sonoma Counties.  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.

The Antennas Direct XG91 antenna is excellent for receiving long distant UHF
channels from Walnut Grove and does well receiving the two local VHF channels,
KGO 7 and KNTV 11.  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 transmitting from the hills east of Red Bluff.

The Antennacraft Y-10-7-13 yagi is pointed northeast toward Walnut Grove and
is used for receiving the two Sacramento VHF channels, KVIE 6 and KXTV 10.
Both local high VHF stations, 7 and 11, also come in fine on this antenna.

The small Antennas Direct SR-15 UHF antenna mounted at the bottom of the
main mast, and shown below, is also pointed northeast and used as a back up
for monitoring the UHF stations transmitting from Walnut Grove.  I use it to
keep an eye on conditions.  It also receives the stations from Sutro Tower
and Mt. San Bruno and some of the South Bay stations quite well off the
side and back of the antenna.  That was a pleasant surprise!

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 six stations from the South Bay.  While it's
a UHF antenna, it receives both VHF channels 7 and 11.  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 one direction we don't
have to worry about where the antenna is pointed and we don't miss any recordings.

The LP345, the all channel log periodic antenna, shown below the CM4228, is pointed
northeast at 50 degrees for receiving the VHF and UHF stations in Sacramento
and Stockton.  It doesn't work nearly as well as the the larger antennas, of course,
but I mainly use it for checking receiving conditions on those more distant
stations.  It also receives the stations from Sutro Tower and Mount San Bruno.


DISTRIBUTION OF SIGNALS

Most 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.


Here are two additional views of the Ability LP345F Log Periodic
antenna, photographed here when it was on a different mast.


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

Reception for four of these antennas, the XG91, HD8200U, Y10-7-13 and LP345
can be seen by viewing the scans from my HD Home Run receivers.
