[Elecraft] Advice on 6 meters...

Jim, you have several CA neighbors who worked me from Ecuador last year.
Yes, they all have very good antenna systems but when 6 is open you can
work many stations, including DX, with a wet noodle.
I have been on 6, intermittently, since 1961 and I *know* you have to be
listening to catch the openings. It is less true today with Internet
access and real-time propagation systems but you *do* have to be
monitoring in some fashion. A great example of this is the day I was
hearing the KH6HME beacon from coastal Ecuador and worked *no one*
during that opening. I had no Internet so could not notify the world and
there was, obviously, no one monitoring since I called CQ for the two
hour period the beacon was in, often at an S5+ signal levels!
A big yagi is nice but for typical domestic operations a smaller antenna
might be better. The big yagi will have a narrow beamwidth and high
front/side and front/back ratios, making pointing critical. A small yagi
or a one-wavelength loop might suit your needs and Sean's as well. I
emphasize the loop because it is simple to build and, if dimensioned
correctly, can be fed directly with 50-ohm coax. Mine was fed at the
bottom and was twice as high as it was wide, with only a ferrite choke
at the feed point to prevent radiation from the feed-line. VWR was under
1.5:1. It's gain, according to modeling I did, was comparable to a 3 or
4 element yagi.
Give 6 more of a chance, I think you'll be pleasantly surprised.

I've been licensed for 50 years and have made only 20 QSO's on that band; 19 SSB and 1 CW. Most likely because I'm not aware that it is open. For me there are a lot of other bands (HF) where at least one is open 24-7 so I simply don't venture up there very often. That being said, I have operated in a couple ARRL VHF contests and was surprised at what I worked. My very first ever 6 meter QSO was with VE7JH on CW back in 2012. The other 19 QSO's included CA, BC, CO, and NE. All were made with a K3 - 100 watts into my 88 foot long, 450 ohm ladder line fed doublet at 45 feet.
