It will even perform well as a satellite antenna on
440. EZNEC says it has a TOA of about 45 degrees.

Hmmm. In some cases, would be nice to keep more of that signal
terrestrial.

That's the subtle point I was trying to make. To keep
the TOA low, the antenna should not exceed 5/8 WL.
6/8 WL raises the TOA. That's not optimum for hitting
repeaters unless they are on very high, very close
mountains.

Yup, the peak of the main lobe is elevated. ... but my 144 copper pipe
j-pole does put sufficient 440 energy toward the horizon that I am often
able to hit a repeater more than 70 miles away (Santiago Peak in Orange
County CA from southern San Diego County). Power out is around 4 watts from
a Yaesu FT-530.

Just now I tried Santiago and didn't hear back, so I tried 449.08 on Palomar
Mountain, 45 miles away, with a half watt and bought it up. Antenna is only
20 ft above ground; house is around 510 ft above sea level on a small rise.
