In 2011 I built a 4 element OWA yagi on a 48 ft boom. This antenna was designed by Rick Craig N6ND and K6NA. It uses all .058 wall tubing for the elements. You can see photos of the building of this yagi here: 40 meter yagi photos Currently this antenna is on the ground awaitng a new tower that I hope to get compleated in 2023. I had this antenna up from 2011 to 2021 and it worked very very well - I am looking forward to getting it up in the air again. This antenna survived an ice storm in Feb 2021.

* This 4 ele OWA yagi has passed through several hands over the years, most recently K5AND. Thank you Dick for a fine antenna. It was orginally built by K7PN for the N5CQ station. K7PN built three of them onsite at the N5CQ station. I would drop by every few days on my way to or from work and watch the progress. Unlike the 40 meter yagi I built this one has slightly larger OD tubing and has thicker wall tubing employing aluminum pipe sized tubes. K5AND got this antenna from N5CQ and made a few changes to it. He replaced the boom to element mounts going from flat plate to aluminum channel. I also think he insualted all the elements from the boom at that time as well. The other change he made was to changing the element spacing and element lenghts, using an electrical design by JK Antennas. This antenna survied an ice storm in Feb 2023.

I have recently setup my station for remote operation using http://remotehams.com/ software. This lets me share the station with family and friends that do not have a station as well as letting me operate when I am not at the station. It has been a fun project. I have an Elecraft K3 and an Icom IC-7300 hooked up to some subset of antennas. I plan on doing more with the remote setup as time goes on to make both local and remote ops work better together. I also hope to add more bands to both radios - including 6m and 2m SSB/CW. I was given a nice rack that I have put all of the remote hardware in to keep it isolated from the main operating position that I keep totally disconencted when I am not at the staiton to protect it all from lightening damage.
The current remote setup is:
Elecraft K3 - KPA500
160 meters
1/4 wave sloping vertical sloping NE and NW antennas
80 meters
1/2 wave sloping dipole sloping NE and NW antennas
40 meters

2 ele shortened yagi at 90 ft fixed NW
30 meters
3 ele JK yagi at 100 ft fixed NE

6 ele yagis at 135 and 85 ft and 45 ft fixed NE
6 ele yagi at 80 ft fixed NW
4 ele yagi at 60 ft fixed SE
15 meters
6 ele yagi at 35 ft fixed NE
6 ele yagi at 70 ft fixed NW
4 ele yagi fixed SE
10 meters
6 ele yagi at 30 ft fixed NE
7 ele yagi at 60 ft fixed NW
4 ele yagi fixed SE
6 ele yagi at 145 ft fixed SW
Icom IC-7300 - 100 watts
Cushcraft R-7000 vertical

I also run a CW Skimmer Server feeding the Reverse Beacon Network. It is using a Red Pitaya SDR connected to a Cushcraft R7000 40m-10m vertical mounted at ground level.
