To get the signal as well as you did at the 5 foot elevation in Hayward, conditions must have been really good tonight. Since Chuck expects unusual reception in the next few days, I'll have to do an occasional check to see what's happening.
UHF reception here is like looking through mini-blinds. Meter says zero,... move the antenna 1 foot left,... meter says 25.... Move again ... zero
Then comes what I call a tidal wave. Signal rolls up, peaks for 5 seconds, then rolls down, with no "Normal" level.
There are sweet spots on the property too. The approx 15 foot VHF circle that pulls walnut grove in. At any elevation, but 12 feet seems optimized.
For KSBW, Tilting the antenna works best.
I'm not sure how a 4228 antenna would work here because of the multipath "Mini-blind" effect. The 4 bowties on the left could cancel out signal from the 4 bowties on the right.
I built a home-made 4 bowtie antenna, it worked similar to a single or double bowtie in the same spot.
Putting a 8 bay bowtie antenna in a spot with poor signal doesn't seem to work any better than a single bowtie in the sweet spot.
I will see if KFTY comes in again ... in the same spot... or it was just a chance event.
I checked for UHF from Walnut Grove that night ... zero ... not a trace
I see signal sometimes from 42, 13, 25 but never a lock.. too low levels.
I quickly tested RF-3 but not finished with that one.
