- Be aware that some cable companies won't connect to RG59. They claim that it's
- too lossy and may require RG6. I looked at the specs, and RG6 does seem to
- have less loss, though not spectacularly so. The number that sticks to in my
- mind is .5db compared to .6db attenuation per 100ft. I forget the frequency
- that's for.
-
- Don't ask how I know :(.
-
- While I'm here, I've got a related question. I live in Pasadena, CA, with a
- line of sight path directly to Mt. Wilson 5-10 miles away (I think) as the crow
- flies. For those of you not in the area, Mt. Wilson is the place where just
- about every station in the area has an antenna. They're all clustered
- together, so I'd expect to get extremely good reception for all channels by
- simply pointing the antenne right at Mt. Wilson.
-
- However, I don't. I receive most of the channels very well, but some (channel
- 13 in particular) are not so great. You can still see it well enough to follow
- the story easily, but it's grainy, ghosty, etc. It's not bad enough to want
- cable, but I'd like it better.
-
- I've tried everything I can think of. I replaced the antenna (we've recently
- bought the house and the antenna was probably old) with the biggest one Home
- Depot sells (I'll eventually move it into my attic, but it's well-hidden as it
- is, so it's not an eyesore). I've replaced the mast with a taller one. Last
- weekend I even went up and strung 100' of brand-new RG6 straight from the
- antenna to the TV. It didn't seem to improve matters.
-
- It's not the incredibly obvious - I just checked, and channel 13 isn't an
- exception to the rule. They do in fact have an antenna on Mt. Wilson.
-
- The current setup is an antenna with place to connect a 300 Ohm lead. Attached
- directly to the antenna I have a 300 to 75 Ohm converter, so I never actually
- use 300 Ohm cable (except the cable which is part of the converter). The cable
- then follows a contorted route to get into my TV.
-
- What could I do to improve the situation?
