I just noticed that I’ve never posted a picture of the completed tower. Here it is.

Mostly Done

The tower is now mostly done. The HF antenna is up, as are the 2m and 70cm yagis.  The rotor is installed, and rotates.  Mostly. There’s a tree in the way of the HF beam, so it can’t rotate.  I have a guy with a boom truck coming to fix that little issue. I still… Continue reading Mostly Done

Tower Grounding

Here's a brief summary of the grounding on my tower as it stands today.  It's not perfect, it's not even ideal.  It's a major compromise. I ran a 2" copper strap from one tower leg to a ground rod about 20' away.  The strap is buried underground, but only about 4 inches deep.  The reason… Continue reading Tower Grounding

Stacking Tower

I'm way behind on updating here.. The tower itself is up. I home brewed my ginpole using an actual gin pole head I bought on ebay.  I added a 10 foot section of 1" galvanized pipe.  I didn't buy any brackets, so I used u-bolts to attach it to the tower.  Not recommended.  And I… Continue reading Stacking Tower

Just a few more updates. The Cedar Rapids Hamfest is Sunday.  I will be on the lookout for a nice 2m Yagi to use on SSB. Tomorrow I will be working on tower grounding.

I don't live on "normal soil".  Our neighborhood is notorious for limestone.  Even the electric utility had issues… Continue reading Tower Construction – Part 2

I have some tower sections

I now have three 10 foot sections of Rohn 25G tower sitting in my yard. I hope to get started soon getting that thing up in the air. I still need a 36″ house bracket. Rohn gets $249.00 plus freight for their heavy duty “universal” model which supports both Rohn 25 and 45 (more on… Continue reading I have some tower sections

Tower – Part 1

Last fall I decided that I would like to start construction of a small tower in spring ’09.  I wasn’t sure how many hoops the city would make me jump through, so I got started on that process nice and early. And I’m glad I did.  Turns out there is a height limit on “structures”… Continue reading Tower – Part 1
