theory and practice

The one on my roof is consistently receiving a 2Edge VHF 8 and 10 from 20 miles out, 90 degrees off axis. ADTech also indicated they saw similar behavior in field tests, just not something they are...

Wow, you must have serious terrain challenges.

The noise margin (NM) says you need gain, lots of gain, at the antenna. That's got to be positive before it even hits the preamp.

grounded

Excellent advice, thank you.

Yeah, that's my soil, and to make things worse, we only get thunderstorms in the summer when the ground has had 4 months to dry out.

On closer inspection, my...

I just use the meter on my Tivo. Your TV might have one buried in it's menu structure.

You might also consider aiming at 316. You'll be surprised at the number of LA stations you can get.

tivo

I went through a similar evaluation process and wound up with Tivo as well. One minor difference was I settled for the previous model (Series 3 HD) with lifetime service from eBay (~$300). It's a...

drops

Are there any near-field obstructions? Trees, neighbor's roofline? Planes on approach to the Carlsbad airport might be getting you some unhelpful reflections, too. On your signal strength meter,...

service ground

You raise an interesting point. Perhaps this is an SDGE thing or a California thing, but for the life of me, I cannot find our service ground. Everything that comes into the exterior power panel is...

Are you getting random drops on all channels or just 8 and 10? Since you're using the DB8, which is UHF only, your VHF reception will be spotty and not nearly as reliable as the UHF stations. Also,...

splitter v combiner

Ha ha, it certainly does, but my question on the AD splitters was whether or not they could also be used as combiners. For some reason most vendors scrupulously avoid indicating their splitters can...

Thanks for the responses

You're in an interesting spot, 4 towers with almost perfect 90 degree separation. I'm up the road from you, and I'm actually trying to pull both LA and SD. You've got a tough nut to crack with that...
