                                                                Mast Project Versatower BP60

 

I got my first licence in 1984 but because of my qrl I had to move a couple of times. Every time I had to find a house with place for antennas and a landlord, willing to admit to drill holes in his house and to build up antennes. And each time I found some of the neighbours with electronic equipment which did not fulfil the electromagnetic standards. So my dream was all the years for the time after retirement to have my own house and a Versatower. I love this typ of construction because it allows me not only to lower the mast when we have heavy wind, but also to tilt it over to work at the antennas more or less from the ground ( I dislike to be high over the ground).

 

A special thank to GM3WOJ, his "Lattice tower information pages" helped me a lot with my tower project!

 

So this is how I fullfilled my dream:

We found a house in the beautiful holiday location of "Muhr am See" with all the infrastructur in the village.

June 2016 I got retired and started to work at the project. I learned that I need a official permission for a tower with more than 10m height and that I need a architecture for the static calculations, the official architectural drawings and so on.

13th August 2016 I bought a used Versatower BP 60 from DJ5BV.

17th August 2016 I gave the application form to the local authorities for construction work.

2nd March 2017 I finally got the permission for construction of the tower.

11/12th May 2017 the basement was made by our local construction company Bau Buck. Originally planned for the next week, but in the late afternoon on wednesday I learned that they wanted to start on Thursday :-)

2 earthpools for grounding are in the basement, each 3m long. And in addition to the normal planned basement I made a 60x60cm head piece so I have the opportunity to fix a winch there.

the big day, 5,25 m3 concret were filled in

 

 

 

good that I put some tape around the screw thread to protect it

 

 

A dream comes true !

 

Now some patience before we can put the tower on the base.  :-)

 

22nd June 2017 the next step!

Still a lot of work, but a lot is done.

 

President Trump wants us to buy american, but when we do, he does not deliver!

Already in April 2017 I ordered two Fulton winches from the US at AMAZON.com because I did not find those strong ones in EU, but I still wait for them  - bad bad bad President Trump !

3rd July I got a message that new estimated delivery will be end of August or in September. So I cancelled the order and ordered the same day at ebay. Already at 4th July I got the message that both are on the way, maybe a present for Independence Day?

12th July I got the first winch, fine and fast, but without a 1/2" -13 locker nut, which is a strange nut in continental Europe where we use centimeters and not inches. So for the first I used an old normal nut which I had. When i wanted to bring the box to the waste I heard a sound and found the missing nut between the folded parts of the box.

I am really glad about this winch, but Mister President - why is this peace of US mastership marked as "Made in Mexico" ????  Bad bad bad President Trump !

 

Here you see the great difference between the old original winch and the FULTON K2550 2500LB (about 1134 kg in continental Europe):

Here how I attached the stainless steel cable to the drum:

So first part is vertical now, waiting for the second winch:

 

... to be continued

 

15th July 2017 finally the second winch arrived:

 21st July despite of my wedding day (39 years) I further worked at the tower (step by step ...):

 22nd July 2017, now vertical rotor mounted and 2 of 3 H constructions:

 

 24th July 2017 despite of some rain I managed to fix the first 3 (of 9) antennas at the tower

  25th July 2017 despite of a rainy day I mounted the next 3 antennas, so already 6 (of 9) antennas are at the tower. step by step ...

1x48 for 23cm, 4x23 for 70cm and 1x11 (out of 4) for 2m1x48 for 23cm, 4x23 for 70cm and 1x11 (out of 4) for 2m

 

By the way, all antennas are Flexa-Yagis, for me they are the ideal compromise of gain, length and wind load and have a high level quality of material. Some of my older antennas moved around with me since 1985 at several locations.

 

 27th July 2017, after a really rainy day yesterday today i could work at the tower again.

So i fixed the rest of the counter weights, so I have 4x10kg weight at the lower side of the tower:

 And I think I will not let the tower stand the whole time at maximum height of 17m, but 14m looks good as standard, antennas have a free look and from the middle part of the tower only 7 of 16 elements are out, so it should stand very stable.

 Still no cable at the antennas and no preamp up, I hope I can do it the next days, keep the fingers crossed!

28th July 2017: I mounted my 3 preamps for 2m, 70cm and 23cm and the splitter for 70cm at the tower, renewed the 12V Kabel for the 70cm preamp, fixed the antenna cables from the 23cm ant to the preamp and from the four 70cm ant to the splitter. Its exhausting how many single handgrips this are. I hope for first tests next week.

 

30th July 2017  READY and initial operation capability !!!!

Ok, I still have to do some smaller things and not everything went smooth, but I am qrv! First qso on 2m and 70cm with the new antenna system in the eve of 29th with DL2AAZ.

 

 

So a dream came true!

 

Versatower BP60 at 17m, I will use him at 14m as standard height.Versatower BP60 at 17m, I will use him at 14m as standard height.
