What was your previous antenna?
What bothers me about this type of antenna is it leads people to believe it has a tremendous range to replace conventional style antennas for fringe reception.
Plotting just the city of Rossmoor you are in the cat birds seat even at 30 miles from the mountain antennas.
It would be interesting to compare it to a Terk HDTVa side by side indoors. It may well have more gain than the Terk, because the Terk is a staggered log design that doesn't have a dedicated reflector.
This antenna should work very well in the LA market where LOS is almost never a problem. Though I think this antenna is over priced.

But that begs the question why not spend that much money on a HBU22. Which has less mulitpath on UHF than any of the above antennas. It will fit on most j-pipes and if needed the boom to mast clamp can be moved back because it's such a light antenna.
Remember that any antenna that is "compact" sacrifices gain and mulitpath rejection simply due to the laws of electromagnetic physics.
