Our tower Construction - This is a Universal 50' tower with two 30" base sections tapered to an 18" top section. The tower should be able to support 30 square feet of antenna. I am using a 15' aluminum 2" mast with a Cushcraft A505S 5 element 6 meter beam at the top. The Mosley is a Super 33 which covers 40, 20 and 17 meters. The beams are turned by a Yaesu G-2800DXA rotator. Work began on August 20th 2008 and finished on November 22nd 2008.

Clearing the top soil on August 20th 2008..

I thought I would hand dig a 5'x5'x6' pit,HiHi!!

Time to rent a mini back hoe to dig in the rock.

The back hoe could only reac to about 4.5' I hand dug the rest.

Three days of digging and exhaustion is setting in.

It is done, 5 cubic yards of dirt has been removed. You can see a boulder bulging out of the back, I left it as a good anchor.

Now came the critial alignment of the first tower section.

I attached the three 6' 30 pound steel legs to the tower. Almost 100 pounds haging from the tower

I plumbed the legs and drove a piece of rebar for each leg to set over to keep them from moving during the pour.

No way to get to the back yard so I rented a Georgia buggy to hall concrete 1/2 yard at a time, almost 5 cubic yards.

It took 12 trips and about an hour to complete pouring 5 yards of concrete, that is appox. 4024 pound per cubic yard or about 10 tons.

Now for the curing.

Cleaned up and ready for the rest of the tower.

Now for the tower assembly.

The tower was positioned so I could assemble a 50' tower a 40 and 6 meter antenna.

I started the assembly of the Mosley S-33 but found a bad coil and had to order it.

I started the fence assembly to protect it from kids and unwanted climbers.

I used marine grade pulleys, all SS bolts and hardware on the tower.

A recommended decoupling coil fro the Alpha Delta sloper.

All surge protectors including rotator are in a DX Engineering weather proof box.

The coil finally arrived from Mosley, 2 1/2 weeks, time to call in the ground crew.

It was a long hard day.

The 6 meter antenna was a piece of cake.

Now for the 100 pound Mosley. It has a 26' mast with three element , the logest about 48'.

It is finally in place and I am making the connections. It was in the 30s that day.

Now we start the lift. The tower and antennas weigh about 340 pounds.

We were only able to get the tower up to about 45 degrees. It was dark and cold and we were tired. So I rented the beast.

This was a self propelled 60' bucket lift. I literally pushed it up the rest of the way.

We are almost there!!

Finally we made it!

The only problem is this beast weighed 22500 pounds, boy do I have ruts to repair!!

Still trying to get the first one in the hole.

The crew- Gary Osborne, W8XS, Myself, KC8RP, Rick Burdick, K8WWA and Paul Flaugher, KB8ANY. What a crew.

The view from the front. Finished tower November 11th 2008.

Atop the bucket lift doing some final work.

My wife Donna without who's support and help this would have never happened!!! By-the-way she was scared s*&%^ less!!!

It was a long way down.

This is a 4"x18"x3/8" copper ground plate outside my shack window.

The only thing left to do is put a locking gate on the fence.

The sloper runs down the north east side of the toer to a post 14' above the ground.

 

I bought a Mosley Pro 67C3 from a ham who bought it new and never opened it, got lucky. The zoning board denied my variance request for 70' so I will reapply for 66', 60' of tower and 6' of mast. I will be able to use my current rotator with a Mosley Pro 67C3. The tower will be able to hold 22 square feet at 60' which gives me plenty of room for the Mosley at 12.1 square feet, rotator, mast and a 6 element 6M antenna.

On July 14, 2018 we are taking down the Mosley S-33 in preparation for tower upgrade and the Pro 67C3. I will take down the tower and add a 10' section I have stored. I have 2 rolls of 7/8" hard line for the new Mosley and the 6M. I will pull up the old conduit to the tower and bury 4" conduit. The hard line can be buried but due to the rocks in the yard they would wear through the cable, the conduit is an added layer of protection. I also will have rotator cable and the vertical coax in the conduit. Later on when I put a deck on the back I will take out the concrete patio and at that time will burry a conduit from the small tower and reroute the antenna and rotator cables through it. I will add a y connector to the 4" conduit for this later addition.

Old Chimney Installation
My first antenna installation occurred during July of 2003.

Cushcraft MA5B with a Yaesu G-450A rotor has been removed from the chimney, the bands were destroying the brick, it was  about 30'. I dug the new pit and installed the 40' of Universal aluminum tower and a 5' aluminum mast.  I have a Yaesu G-800DXA rotator to replace the G450A, it can be radio or computer controlled.

=======================================================================================================================================

New tower installation for MA5B
New tower started on November 11th 2013 and finished July 12th 2014. Winter storm hit just 2 days after I poured the base.

The weather was cold and a storm was coming.

The 3' x 3' by 4' hole is dug, next I will put the forms in.

Formed up and ready for the lower tower section.

The 18" base and legs are braced and set in place.

Spent a lot of time leveling checking and rechecking, concrete is final.

I drove in 3 pieces of 2' foot rebar to center the legs at the bootom of the pit. This will keep them centered when the concrete is poured.

Waiting for the concrete truck, the storm is due tomorrow.

All poured, now to cover it up and wait for the storm to pass.

I removed all the forms and now I will let it cure for a week or more due to the cold weather.

First 3 sections installelled.

The final section has been added and the antenna attached.

At first we thought I would lift the antenna and Rick would reposition the latter under it.

After taping the cable to the tower I soldered on a end connector.

I used one of my articulating ladders to extend the tower higher.

With all that mind power it was my wife who suggested 2 ladders, one to push it up and one to hold it, Genius!!

My neighbor Barry came over and gave us a hand, great neighbors!

Putting in the final bolts.

The gang with my neighbors wife Becky. My wife, Donna, is taking the pictures.

Backyard view of the antenna.

Side yard view.

Final view from the front of the house.

I ordered a 14" top section for the tower and two 18" bottom sections, the tower will be 50' tall. I just acquired a Mosley TA-63N, a 20 through 6M antenna to top it off. As soon as Universal Tower lets me know the tower sections are ready, ordered 8 July 2018, I will upgrade the tower.

I have nine 4' fiberglass sections of military field antenna masts. I can go as high at 45' with the guide ropes which should have no problem supporting the MA5B. With the boom only 7.3' and weighing 26.5 pounds makes it an ideal match with the masts for field day and other events.

=======================================================================================================================================

Hy-Gain AV-680, 80 thru 6M on a fold over mount with the base 10' above the ground. The new vertical is mainly for 80 and 30M, a backup never hurts. I mounted it to two 4x4s 10' long with 2' buried in the ground. This is not permanent but adequate for the antenna. I have to repair the antenna, burnt something out not sure yet. I was working 80M SSB and switched over to FT8, forgot to bypass the amp, did not last long on 800 watts, three 15 second transmit cycles on FT8, GRRRR! The antenna is very narrow in band width, auto tuner can only handle a small range, will need a good manual tuner for most of it. I chose this antenna because I do not have the room to run radials.
