About October of 2015 I decided to investigate the option of using something other than a vertical antenna on 6 meters. I'm not sure it really makes much of a difference during a 6 meter opening when everyone else is horizontally polarized from a few thousand miles away like stations booming in from Japan on a good 6 meter opening. Anyway, the first option I investigated was simply adding 6 meter traps to my 40/80 meter trapped dipole. That option was done and dusted when I received an email back for the manufactures of my existing traps that said they do not make 6 meter traps. Possibly one day I will purchase two 10 meter traps and disassemble them and try my luck at converting them to 50 Mhz. Next I did numerous Google searches for commercially made 3, 4 and 5 element 50 Mhz yagis and tried to compare prices, performance, wind loading, shipping cost etc. etc. But one search that caught my eye was to simply add six meter elements to my existing 10, 15 and 20 metre HF tri-band yagi !!!

If you are interested, please read the PDF thoroughly. I did not use 1/2" and 3/8" aluminum tubing as specified in the article. I used 1" and 7/8" aluminum tubing from an identical tri-band HF yagi that had been damaged. After tuning up the 6 meter elements one meter off the ground supported by plastic rubbish bins as seen the photo below, the over all element lengths were approximately 2% shorter then specified and the distance between the tri-band driven element and the 6 meter parasitic driven element was 6 1/2" rather then 10" as the article specified.

Also, the 6 meter reflector and director are electrically connected to the tri-band boom and the 6 meter parasitic driven element is insulated. Why, because I used all the same aluminum brackets and U-bolts from the old HF yagi.

And last, after hoisting the modified tri-band HF yagi in the air, the SWR graphs as per the SWR meter readings on the FTDX-1200 and the MFJ-226 hand held antenna analyzer.

Made three contacts to Japan on 6 meters the day the modified tri-bander went into the air.

Yep, those are uncut cable ties to try and keep the White Corella's from eating through the coax at the feed point as they have done a few times in the past. I've given

up on the black Low Density Poly Ethylene plastic trap covers as seen in the photo. The first 2 meters of coax is also sleeved inside garden hose for protection too. I'm

not sure what the birds like about LDPE plastic.
