Smile Help with antenna selection in Wa?

Hi folks,

Here's my TV map: http://www.tvfool.com/?option=com_wr...60b56f2de6febd

Basically, I want to get the Vancouver stations from -9 to -16 NM dBm that are about 100 miles away.

Is that even possible?

Currently I have the V-shapped antenna, like from Radio Shack VU-190 or something pointed directly at those stations.

Before when they were in analog form, I could get channels 2, 6, 8, and 10. Now that they're all digital, of course I didnt expect to get them with my current setup since they are in UHF and their ERP is so much lower, though channel 43 CBUT is at 100kW.

The farthest I can get is channel 35 (12.1 KVOS) and KCBC 24 that is about 60 miles away.

I have RG 6 cable that is about 100 feet with combiners in between them serially.

Of course, I know I need to get an amplifier to eliminate the signal loss down stream...

So... back to original question.. can I get those channels with up to -16 NM dBm?

I read that the DB4 or DB8 has a gain of about 15 dbM, which would bring me to almost 0 dBm?

Or, that Lava 2605 (that famous 'get channels 150 miles away' advertising), where the spec they gave on their website is up to 30 dBm gain, which would bring me to +15 NM dBm.. is that for real, theoretically?

Another tidbit, that channel 22 with ERP 40 kW, on some days, my tuner would show a signal "blimp" for it, so that gives me hope that it faintly detects some signal with my current rig...

So , would a combination of amplifieri and new DB4/DB8 or that Lava 2605 antenna help me catch one or two Vancover stations?

I don't wanna move just to watch non-traditional TV....
