Whose towers?

B

beachguy3b

As I drive to and from work daily, I pass a 4 tower array on the north fringe of 101, with the towers being east of 101.

Who's towers are these?

Thanks!

You don't say what town but by the phrase "north fringe" I trust it's at a latitude 38 or higher. That would probably make it KCBS. Does 740 come in really well there?
 
It's KCBS. Those towers direct a 200 Kw main lobe straight down the Bay, with about 12.5 Kw daytime and 5 Kw nightime going north towards Santa Rosa.

And an unfortunate nighttime null that pretty much follows I-80 towards Sacramento.
 
The blast down here in San Diego at night. Sounds like they are next door!

KCBS does, in fact, shoot most power SSE, with a minor lobe just good enough to cover the northern parts of the San Francisco metro... which goes all the way to Santa Rosa. The differences in day and night coverage are really not noticable in most of the metro.

The best fackility is KGO, which has the same constants day and night. The pattern is symetrical, with equal power headed at 340° and at 160°, meaning roughly that the major and identical lobes are aimed NNW and SSE. The nulls are sharpest at 70° and 90° with a tiny minor lobe at 80° to the east, with identical nulls 180° opposite.

So, Campbell and Santa Rosa each have about the same power aimed at them.

For both KGO and KCBS, there nothing unfortunate about the nulls they have to the east, which avoid spilling power over an area outside the San Francisco market... because there is no added revenue for listeners on the other side of the hills.

Out of market doesn't make much difference, but I'd say the best pattern is KNBR. You can hear it in Santa Fe, but you can't hear KGO in Santa Fe. Plus, KNBR covers the SF market thoroughly without those annoying nulls.

Just sayin.....

In the 60s growing up in the San Fernando Valley (LA), my mother would listen to KGO at night - Ira Blue, IIRC. KGO came in as clear as any local LA station. I would listen to 610/KFRC, which would fade in and out a bit, but generally had a good signal into LA, despite being only 5,000 watts. I probably also tuned in KNBR (MOR in those days), and KCBS, but don't recall - MOR and news were boring to my 15 year old sensibilities.

It's interesting that SF stations reach LA better than LA stations reach SF. This goes back to the fact that SF was once the west coast media hub and station owners paid more attention to SF stations than LA owners paid to LA stations. Thus we get a 50kw KGO while LA has a 5kw KABC; NBC had a 50kw KPO/KNBC/KNBR but had nothing in LA. Well, there was KFI, still the best LA signal reaching SF. But you look at the various stations and it's clear that LA was actually not considered as important in the early days. And then of course with grandfathering, there was little they could do to catch up.
