Yes there is... (see attached)
I have both a preamp and a dist. amp that both have FM filtering.
Would FM frequencies cause worse interference in colder weather or when the sun is setting?

Thanks

How about posting the link to your TVFool plot so we can get an idea of what the signal situation is expected to be at your location.
like this? it reads more bleak than it is:

Essentially, I have two silver sensors on a pole, one pointing to LA, one to San Diego. I get very little, if anything, from LA.

You'd need to put a LOT more metal up in the air along with an appropriate preamp. The calculations in your plot suggests that it's doable, but you'd really need to step up your game. If you happen to have the good fortune of a clear signal path towards LA, that would be quite an advantage.

any examples or links of what a lot more metal may be, and when you say preamp, I'd also need to get AC up there as well?

Your best shot to LA are the VHF stations (7, 9, 11, 13 at the moment) and there will be more after the repack. So, you will want a VHF antenna at least for VHF-Hi unless KVCR moves to Mt. Wilson on Lo-VHF. We will know in about a month if there will be more Lo-VHF's here as well.

First I want to ask if your 2 Silver Sensors are on the same cable run? If so, get a switch or rotator (commonly just called a rotor). Two antennas pointing in different directions can result in unexpected patterns and make things worse.

Try a new antenna before a pre-amp, but you are probably going to need one. What coax cable are you using? Make sure it's RG-6. A pre-amp doesn't need an AC outlet on the roof. The power is fed thru the coax.

Knowing that VHF will play a larger role, I would suggest something pretty hefty. Something like this, perhaps:

If you don't care about Lo-VHF/FM:

If you do want Lo-VHF/FM:

http://www.solidsignal.com/pview.asp?p=hd8200u

This thing is huge (14' long and 9' wide) and it's probably best to wait for the new channel allocations to come out to bother with this, unless you want FM too. My Uncle lives in San Clemente and even LA FM radio is tough there.

You would keep the preamp in the attic or use one that utilizes a DC inserter on the coax.

ALL modern preamps are connected that way.... If it doesn't connect that way, it probably isn't a preamplifier.

Right. Like the one in my closet. A distribution amp. I don't need a preamp at my location and they are different things.

Pre-amps are mounted at the antenna mast or as close to the antenna as practical so as little noise is amplified as possible.

Just a curious question from an out-of-market visitor...is there actually an LD station called KSFV-6 somewhere in LA???

edit: deleted the rest of my post, think I finally found the answer here...so evidently DISH just upgraded it this week to HD. And with Sinclair involved, makes perfect sense as to how this got on DISH!

BEVERLY HILLS, CA--(Marketwired - September 25, 2015) - Greek Billionaire Alki David's FilmOn Networks announced today a massive slate of college sports to broadcast on FOTV, the cable channel that can be viewed on Dish Network and Charter Cable in Southern California. The games are presented in a partnership with Sinclair Broadcasting's American Sports Network. There will be up to three live broadcast of games each Saturday representing major teams and conferences from across the nation, all games you can't see anywhere else in the region.
FOTV is also on Dish Network channel 6 in the L.A. market, between KTLA and KABC, running 24 hours a day, and over the air on KIIO channel 10.2. It is also on Charter Communications at channel 387, spanning from Burbank to the San Gabriel Valley.
Sorry for the interruption...

Balanced or Unbalanced 3 way antenna combiner?

I am going to combine 3 antennas.
Should I get a Balanced or Unbalanced splitter?
