Thanks for the input.
Rabbit73, I do not have a UVSJ thus the disconnect.
Tower Guy, thanks for the info & link. Its been a long time since I had a physics class looking at waves and their resonance/dissonance effects from reflections
. However, the diagrams make a great explanation on why I had a vertical band. The reflection off of the pavement would also explain the lateral distance that I was able to get feed.
So what this seems to be telling me is that there could be KTMF signal at my mast location, but without the added strength from the reflection the antenna doesn't pick it up.
My current pre-amp (Wineguard LNA-200)
specs say it has an 18 db gain. The
Kitztech that Mikebear uses has a gain of 24db. It would appear that switching pre-amps could provide up to 30% boost in signals at my current location; however that may or may not be enough with the current set up to "get" a signal. From Tower's post it would appear that the band that I got signal could have been up to 400% of the signal that is hitting other areas of the house.
Question:
1) Would I be correct in thinking that just changing the pre-amp will not be enough to get signal at my current mast location?
2) What numbers do I need to get from the Stacker manufacturer on its UHF gain to be able to compare with other UHF on the market? (i.e. if they tell me that its UHF gain is ~10 db then I would think I need something 20-30db gain to pick up a signal at my current location).
3) Is there any way to estimate what the strength level was when I picked up the signal (and thus allow me to reverse engineer what I may have at the mast)?
Appreciate all the help.
