60 Ft HD16-60 Universal Aluminum Tower:

My wife Pat and I, put this tower up in August of 2001. I had purchased a used 50ft tower from a ham in Indianapolis, IN and then added a used 10ft section purchased from another ham in Minneapolis. The base section is 30" across and 7 cubic yds of concrete anchors it to "Mother Earth".

The resulting tower is rated at 16sqft at 80mph and is 60ft high. The antennas atop the tower are as follows:

432 Mhz -- K2RIW 19 element yagi at 68ft

1296Mhz -- Directive Systems 45 element loop yagi at 66 ft

222 Mhz -- Cushcraft 220B 15 element yagi at 65ft

144 Mhz -- Cushcraft 13B2 13 element yagi at 62ft

902Mhz -- Directive Systems 33 element loop yagi at 61ft (3/07 Temporary)

50Mhz ---- Cushcraft A50-5 5 element yagi at 60ft

All feedlines are individual and are Andrew LDF 1/2" hardline or better except for the 50Mhz yagi which uses RG8 foam. Rotating loops and jumpers are 9913.

Dipoles and inverted Vees for 80, 40 and 20 meters are also supported by the tower.

Hinged Base:

Universal talks a lot about "assembling the tower/ antennas and then walking it up". Well, working alone 30ft of the tower was all I could handle. The rest was pulled up and set with the help of a gin pole. The aluminum sections are very light weight compared to the Rohn 25G sections that I am used to working with. The horizontal braces are at times a bit far apart for comfortable climbing on.

Our cat Gizmo has to check things out and be sure that dad doesn't do anything dumb!

Money Down A Hole:

The base section is 30" across and 7 cubic yds of concrete anchors it Mother Earth .

56 Ft Delphi DMX Tower: (Tower on the right)

I put this tower up in June of 2011in the footprint of my old Rohn25G. I had salvaged the TV tower about 10yrs ago. It started as a 64ft tower and I built a top plate and new rotator plate using only 56ft for a bit more strength. The base section is 29" across and 3.75 cubic yds of concrete anchors it. I dislike the "X" braces, but it is a better tower than the old Rohn 25G for unguyed applications and my 10Ghz system.

There seems to be quite a few of these towers in our area. They are similar in design to the Rohn Spaulding HBX series of towers except they are a straight taper tower. That makes "plumbing" the tower when pouring the base kinda tricky. There was too much wind for a plumb-bob too.
