I realized there was an old outdoor antenna mounted on the chimney. The longest leg @ the right end of the antenna was lost (see attached pic).

I realigned the antenna's angle so to point to around 319° (true north).

I got almost every channel I needed,


except KGO (ABC Ch 7, 44.3 miles @ 319°, power -46.9dBm) where I got nothing. On the Channel Master CM-7000 it showed 0-20% signal during the day. No pic. Occasionally a picture came in, and soon it disappeared.


KGO is the only VHF channel I want right now (all other channels are on UHF as far as I am concerned).

** There were a few tall trees about a block away from the antenna along the line where the antenna pointed toward (319°). They were taller than the antenna. Not sure if they posed any obstruction.


Other channels:
KRON - 44.3 miles @319° signal @ 60-78% (@ night 28-40%, occasional pic freeze).

KTLN - 71 miles @ 329° signal @ 55-78% (@ night 40%). It dropped to 0% from time to time (day or night), causing pic freeze every minute or two.

This was with a direct connection (no splitter).

----------

Going thru' a 3-way splitter (7dB signal drop),

KRON signal dropped from 60-78% to 20-33% (occasional freeze) during day time after the 3-way splitter.
Some (not all) of the channels that got 100% dropped to 50-68% signal during day time after the splitter.
Channels that got about 50-60% (5-6 channels) dropped to 28-30% signal during day time after the splitter.

I will eventually need a 4-way splitter (7 to 7.5dB drop).


I think I'd need a better outdoor antenna than the one I have now to capture the VHF channel KGO (ABC Ch 7) and to compensate for the signal drop for some of the semi-weak signals for some channels.


Would ANT751/HBU22 work better than my existing outdoor antenna and be strong enough to pick up KGO (with 7 - 7.5dB drop going thru' a 4-way splitter)?
