For a start, G8MNY has sent out a few recently:
Msg# TSLD Dim To @ BBS From Date/Time Title (LC-choice: *)
34208 BF 3855 TECH @WW G8MNY 0401/2134 6m Yagi from TV Antenna
34174 BF 3104 TECH @WW G8MNY 0331/1719 6m 6el Yagis
34171 BF 2467 TECH @WW G8MNY 0331/1619 6m 8el Yagi
34132 BF 4037 TECH @WW G8MNY 0330/1636 2m & 6m Band "Neptune" Aerial
And virtually every ham handbook in the last 50 years has had a
few 6m antennas.
It is easy to add a 6m element to a spider type quad, but I'm no
fan of the quad. I'm using an ancient 5 element commercial 6m
yagi that the wind has broken down to just driven element and
reflector and I'm still able to work 300 miles on CW with my 857.
And its only 15 feet above the ground.
In earlier times, I had a 80 meter double extended zepp up and
built an antenna tuner for 6m and it worked very well. I made
many contacts with that. I haven't yet tried to do that to my
present 80 meter inverted V, but if matched at 6m it may get out
too. HF yagis probably won't get out as well as the tuned center
fed wire, especially those with some sort of match at the feed
point.
When 6 is open for sporadic E propagation, a wet noodle is an
adequate antenna, when its not open, 7 elements on a 30 boom
makes a noticeable difference. But I've know of daily morning
tropo contacts out to over 1000 miles from local hams running
power and a single large 6m yagi.
