I purchased a K4KIO Hexagonal Beam 4 years ago on the advise of my friend, Jeff May, W0XV, in Brookhaven, MS. A hurricane had taken down a lot of trees at his place and it brought down his tower and antennas. He purchased the K4KIO Hexagonal Beam and has been extremely pleased with it. He has put up several of these beams for friends and they all seem to be very pleased with its operation, even at low heights.
This is a picture of a completed K4KIO Hexagonal Beam (not mine):
Like I said, I purchased my K4KIO Hexagonal Beam four years ago and had not put it together. Things like work, grandchildren, and the failing health and death of my father took a toll on my time.
The K4KIO Hexagonal Beam covers six bands, 20 through 6 meters and is fed by a single coax. It has low SWR and no tuning is required. It has improved broad band response over the original hex beam design and performs well at lower heights. It also handles full legal limit power. It has a small physical foot print and is light enough for a push up mast. The symmetrical shape withstands wind better.
I am really not happy with the mast that I will be using and I am continuing to look for a better alternative. Currently I will be mounting the beam on a Rohn 25′ push-up mast with a Yaesu G-450A Rotator on top of the mast and the Hexagonal Beam on top of the rotator. I really want to get the antenna up to at least 40 feet minimum.
I took my last day of vacation on Friday, October 2nd and I got up and mowed the yard. Hopefully this will be one of the last times this year I will have to mow grass. But I will probably have to mow it at least one more time. It had turned cool that day and the highs were in the 60’s, a big departure from the low 90’s. After lunch I got the boxes for the K4KIO Hexagonal Beam out of the garage and started to put it together. I knew because of the time I had that I was not going to be able to finish it on Friday because we had to go to our Son-In-Law’s football gave he was coaching in Columbia, MS that night and it was over an hour’s drive.
I bought the version with 20 through 6 meters on it. First I mounted the “P-Clips” with hose clamps to the bottom section of the spreaders, 34 inches from the bottom. This is for the 6 meter wires to run through and were not pre-mounted as the rest of the bands were. You can see the bottom sections on the table below with the “P-Clips” mounted:
The picture above shows the rest of the spreader elements and the center post in the cardboard tube waiting to be assembled.
I spent about an hour and a half on Friday afternoon unboxing the parts, reviewing the instructions, getting the few tools needed to assemble this antenna, and mounting the spreaders to the mounting plate. Like I have said, this was a simple assembly. When I finished on Friday afternoon the picture below shows the progress for the day:
I had to get cleaned up and ready to leave when my wife got home from work for the football game in Columbia, MS. I could have finished the assembly Friday afternoon except for the football game. We got home from the game around eleven that night and we had to be at a Pee-Wee Football Game in Petal, MS Saturday morning at ten. Our granddaughter was cheering at the game. After lunch we headed back home and I was very tired from the short night and I ended up taking a four hour nap and it was dark before I woke up. To say the least I did not get anything done on the antenna on Saturday.
Sunday after lunch I got out and finished assembling the beam. My wife came out and helped me run the wires for each band, so the task went quickly. I mounted the Center Post and then the Support Lines and then we ran and attached all of the wires for each band and wire-wrapped them. Here are some pictures of the finished product:
I have not purchased the mast pipe to go on top of the rotator yet and I will get one at Lowe’s this afternoon after work. I will try to get a 10 gallon bucket to fill with bricks and sand so that I can get the antenna up off of the ground and test the SWR on each band before putting it up on the push-up pole.
I am going to mount the remote coax switch out on the push-up pole so that I can switch between this beam and the 80-10 meter Carolina Windom I am putting up later. I do not have any trees in my yard because of our experience in Hurricane Katrina, so I will mount the Windom on a 50 foot fiberglass push up pole. Before Winter sets in I am going to put up a 43 foot vertical just for 160 meters. I plan on purchasing the MFJ-2910 160/80M Matching Network for the 43 foot vertical. I already have the ZeroFive 43 foot vertical and a top grade 1:4 Unun. I will be feeding it with LMR-600 that will give me plenty of current handling capabilities. At that point I should be ready on 160 through 6 meters as a little pistol station! But I do run QRO with my Ameritron AL-1500 amplifier, Alpha 76A amplifier, and my Heathkit SB-200 that has been converted to a 6 meter only amplifier. Hopefully this setup will get me into the logbooks of the upcoming DXpeditions and contests!
I will have another entry after I get the K4KIO Hexagonal Beam on the air!
