I run both loops and Yagis in my attic, and while the loops are far easier,
they don't match the performance of the Yagi's. I'd certainly vote for the
Directive Systems "Rover" series of Yagis. The only modification that mine
required was to move the "U-Bolt" to the true center of the antenna to shorten
the turning radius.
I had thought about the Par Electronics Maxxon's but went with a 3 element Yagi
for 6 Meters instead. It just barely fits due to the element length, not the
boom length, but it works very well. I've been able to work almost everyone
that my nearby friend and neighbor does on 6, and he's running 7 elements at 75
feet and 500 watts. As many have said, when the band is open, it's open!
If you're interested in WSJT for 2 Meters, a smaller beam actually has been
proven to work better than the bigger Yagis. The reason is that a 5 or 6
element beam has a much wider beamwidth and "sees" more of the sky...this
provides a larger number of potential "pings" to carry the signals. Optimum for
WJST seems to be 6 elements. There was an article a while back in CQ VHF about
tests done in NZ and AU on the subject.
Indoor beams will never compete well with outdoor antennas, but they can be
made to perform pretty darn well.
