Hi guys,


Recently I had an LM-470 crank up and JK Mid-Tri-40 installed. I'm in the planning stages of stacking another Mid-Tri below it. JK recommends 35' separation which puts the bottom antenna near the top of the 2nd section from the bottom.  The obvious choice would be a ring rotor. Although there are no prices for the 1022D or 1122 on their site, unfortunately I'm pretty sure they're out of my price range. 


Plan B is to side mount it fixed for the flexibility of having another direction.  Is there a commercially made mounting bracket that would fit an LM-470 tower or will I have to have one fabricated? 


Thank you,


Mike, NT6X

There is a better option than fixed. You don't get full rotation but it gives you something!

You should have a 50:1 reducer.

Over the past few weeks, I also have been trying to rehab a HUB CITY gear box.  This is the unit makes up the heart of what is seen in ham radio catalogs as the MD-75 motor drive, commonly used for lifting of crank-up towers or to lay retracted towers over.  Hub City would NOT deal directly with me but with a ‘dealer’ which could represent a company that they supply.  What I had to do was to call Hub City, get them to send an exploded diagram of the gear drive unit, and then order the parts related to the drawing through a dealer located in Orlando, Fl.  So far this process is ongoing as the order has not been filled. But I am hopeful that soon I’ll get a call that the parts are available and the cost for them.  It seems like a round-a-bout way to do it, but as I said, Hub City would not sell direct to ME.  I’ll report back here with the results if and when.  ’73, Mike K4CVL

Re: Hole for Wonder Post

John
 

Hi Chris,
I installed one in Dunedin, FL by adding on to the length of the post-hole-digger handles.  Here is a picture.  I bought one of those cheap green 6 foot fence posts and cut it in half and bolted it to the wood handles.  Good luck.

Re: Hole for Wonder Post

Great minds.  I dug a four foot deep, 18" diameter hole for my DXEngineering tilt over mount for my 160 vertical. https://www.dxengineering.com/parts/dxe-va-pivot-3

The soil in the chosen spot is compacted decomposed granite (like really coarse sand) with a few rocks thrown in.  When the hole got so deep that the post hole digger handles were hitting the sides of the hole, I broke out the shop vac.  Rocks too big to go through the hose were just held by suction while I brought up the hose and removed them.

I was able to keep the hole precise enough that I almost had to hammer in the 18" Sonotube.

I have the same mount for my AlumTower. If you are not in too terribly rocky ground a shop vac works great. Dig the first couple feet with a post hole digger and shovel.

It is not too difficult to empty the shop vac every so often. I attached the nozzle of the shop vac to a pole so It was easy to control it as it gets deeper in the hole.

My tower survived Hurricane Irma a couple of years ago so I know the MP-2 mount is very stable.  When you backfill just run some water into the hole as you go and it makes a pretty solid mount. 

Even if you burn up your shop vac (you won't) it is cheaper than a backhoe and makes a much more compact of a hole. Have fun and enjoy the new tower!
