    Help Getting KNTV in Downtown San Francisco

    I recently got a new TV and antenna and cannot pick up a signal for KNTV at all. I am looking for any suggestions on how I can get that channel, including better antennas to buy, if necessary.

    Here is my TV Fool report:
    TV Fool

    I live on the fourth floor of a five-story building in the 94109 zip code. My only window faces north (not including the west-facing window in the bathroom). I receive KGO, KPIX, KTVU, KRON, and KBCW with basically no problem. KNTV has never shown up no matter which direction the antenna is facing or what height it is at, though my options are limited. On a side note, a neighbor right around the corner from me does receive KNTV.

    My current antenna is an RCA ANT1400R Multi-Directional Digital Flat Passive Home Theater Antenna.

    Any advice will be greatly appreciated!

    I think any channels you are getting from the south are the very strong ones, and the stations to the South are passing through a number of obstructions (including other apartments) I THINK your neighbor probably gets KNTV because they are in a better location.

    Also, KNTV is VHF-hi, and your antenna is designed for UHF.

    The first thing I would try is getting a pair of cheap Rabbit Ears, which are designed for both VHF and UHF, and a length of RG6 coax long enough to reach different places in your apartment, and a barrel connector. Hook it all up and find a sweet spot in your apartment that works for KNTV.


    Another suggestion is to place a small outdoor antenna outside your bathroom window and aim it south.

    SFDani,

    I like Mr Pogi's suggestion to try rabbit ears. First, try them extended 'barely' under 11 inches on both sides with the elements horizontal or flat. If that doesn't work, keep testing by changing both sides equally in arc-height (as in a 'VEE') and extend the elements a bit, rescan your tuner, extend and rescan... The elements should be 'broadside' toward the transmitter. Please report back about your results.

    First, Thanks for the suggestions. However, my antenna is supposed to pick up UHF & VHF. And I thought KGO was VHF, and I never have any problem with it. Also, I don't live in an "apartment" in a traditional sense of the word. It's a roughly 10x10 room, so the 6' coaxial cable I currently have just about reaches throughout the whole place. Money's tight right now, but I'll try rabbit ears if I can get them.

    I found the manual for the 1400R, and whaddaya know? It says VHF and UHF. I'm not sure I believe it. Usually those little plasticy things are useless for VHF.

    Anyway, all the stations you list are southwest at 206 degrees magnetic; the station you don't get is directly south at 173 degrees. So you need to think about what is blocking your signal from the southwest that's clear to the south. As long as you have enough cable and an antenna that's sposed to get VHF, you could try moving that around a little more -- especially near your west window. And if you can get your TV on a cart, maybe you could wheel it, and the 1400R, over to your neighbor's apartment. If it can't pick up KNTV from there, you know your antenna isn't good enough. Outdoors, that signal would be very strong at NM = 65 dB.

    Just because a manufacture says an antenna picks up VHF doesn't mean it does it well. For the efficient reception of high VHF (i.e. real channel 12) you need a 29" long dipole. That is why a cheap rabbitear loop combo antenna like an RCA ANT111 or ANT112 may work better than the flat antenna, which isn't large enough to pick up high VHF efficiently.

    You mean the engineers at RCA are not able to change the laws of physics??
