getting more channels
 
I got the available channel list from the site. I bought a DB2 antenna and put it indoor. I can only receive WJCT, WTLV-DT(NBC) and WJXX-DT(ABC). Why couldn't I get Fox and CBS? Their towers are next to ABC and NBC according to the map.

WAWS-DT 32 (30.1) Fox 13.6 LOS 64.9
WTEV-DT 19 (47.1) CBS 13.6 LOS 64.5
WJXT-DT 42 (4.1) Ind 12.5 LOS 63.7
WCWJ-DT 34 (17.1) CW 13.1 LOS 63.4
WJEB-TV 44 (59.1) Ind 13.1 LOS 61.5
WJCT 7 (7.1) PBS 13.6 LOS 45.2
WWRJ-LP 27 (27.1) 13.6 LOS 44.7
WUJF-LP 33 (33.1) 13.6 LOS 43.8
WTLV-DT 13 (12.1) NBC 12.5 LOS 42.2
WJXX-DT 10 (25.1) ABC 12.5 LOS 40.5
WJXE-LD 18 13.6 LOS 38.4
W45BZ 45 (45.1) 13.6 1Edge 26.2
WPXJ-LP 41 (41.1) 19.8 1Edge 23.1
W54CS 39 (36.1) 19.7 1Edge 23.0
W50CO 50 (50.1) 19.8 1Edge 21.0
WPXC-TV 24 (21.1) ION 50.4 2Edge 17.4
WJGV-CD 25 44.9 2Edge -14.9
WUFT-DT 36 (5.1) PBS 68.3 Tropo -17.2
WACX-DT 40 (55.1) Ind 111.0 Tropo -19.6
WMFE-DT 23 (24.1) PBS 109.8 Tropo -19.8

Thanks,

Please post a copy of your TV Fool Report.

How many sets?

How much and what type coax?

How many amplifiers, make & model?

Building construction... brick, wood, concrete. metal siding or foil faced insulation?

Thanks

I'd start with antenna aiming.

The aiming of the antenna is complicated because you are trying to receive VHF stations on a UHF only antenna. The existing aim may be optimum for the VHF stations, which you are receiving OK, and causes the intended UHF frequencies to be attenuated.

Ultimately, you should get a VHF/UHF antenna.

Here is the report. I thought all channels with green background are in UHF.

Please take the time to read the signal analysis FAQ that is linked to at the top of the report. You will see that you have three VHF stations in the green part of your list. Prior to the analog shutdown, those three may have been using UHF frequencies for digital broadcasting, but they are not now.

TG is right, you need a high VHF/UHF antenna. Something on the order of a Winegard HD7694P or an AntennaCraft HBU-33 should get everything you want.

Thanks for posting your TVF Report.

Yes... confirm the aim. Panel style antennas should 'face' the transmitter they are aimed at. http://www.kyes.com/antenna/pointing/pointing.html

Did you use the matching transformer (balun) supplied with the DB-2? Do you have any reused or salvaged parts in the system? Did you have to install coax connectors on any of the cables in your system? What about the previous questions?

As you look at your TVF Report, the second column titled 'Real' lists the RF channel number the station is broadcast on. Chanel numbers 7 through 13 are known as High-VHF channels. Each of the stations you listed are in that band.

I would expect to need a H-VHF antenna in addition to the UHF only DB-2 (a good choice for your location). I'm thinking an Antennacraft Y5713 which can be combined into the existing coax with a UVSJ.

To keep things compact you could simply switch to a combination (dual-band) antenna like the Antennacraft or HBU-33.

Until you sort out the problem with the existing antenna, don't rush out and buy another antenna though. If mounted outside, facing NW, the DB-2 should receive all of the UHF channels from the top of your report down to WPXC with one possible exception, WQXT.

You say the DB-2 is inside, have you tried it outside?

The VHF stations are:

WJCT on channel 7
WJXX on channel 10
WTLV on channel 13

If the antenna is mounted on the roof possible solutions are:

Add a Y5-7-13 to the DB-2 with a UVSJ
Replace the DB-2 with one of the following:
HBU-33
HD7694P
ANT751

Out of curiosity, where did you learn that all your stations were on UHF?
