K9ZW Antenna Transition – Big Hex Beam Dismantled and Stored

The Big Radiowavz HexBeam never made it to the top of the tower. As you can read in https://k9zw.wordpress.com/2020/07/20/skyneedle-and-hexbeam-slow-progress-and-other-tasks/, https://k9zw.wordpress.com/2020/10/03/deer-damaged-hexbeam-repairs/and https://k9zw.wordpress.com/2020/12/03/a-change-in-antenna-direction-at-k9zw-home-qth/ the physical build wasn’t up to my environment.

Over the Christmas weekend I dismantled it and started the preparation for storage.  Photos were taken to document the areas I hope to improve in the eventual rebuild.  In the disassembly a few additional areas of concern appeared, which I will be digging into as part of the redesign.

It was about 20F (-7c if you are Celsius-minded) but otherwise a nice day to work outside.

I have a couple other hexbeams and have started to dig into the hexbeam literature on the web, so I hope to get the redesign done over winter.

Though RadioWavz has gone radio-silent on me, in my research I found they had addressed some of the issues – see https://youtu.be/ybbp_iC7HtU for a build of a smaller RadioWavz hexbeam.

Whether I can effectively retrofit the later upgrades is something I can explore.

Provided the rework is cost effective, there is a chance the antenna will go back up in 2021.

If the costs look to be excessive the “fish or cut bait” maxim will force a decision to abandon this particular Hexbeam project.

Deer Damaged Hexbeam Repairs

While on the ground Whitetail deer got into my hexbeam.

It must’ve been quite a sight to see a deer wrestling with the hexbeam.

Mostly wires just got pulled around, but one support arm element was broken in the wildlife ruckus.

Easy to pick out the broken support – the collar is already relocated on the unpainted new part.

Skyneedle and Hexbeam – Slow Progress and Other Tasks

Have been working on the Hexbeam replacing the Generation-One wire guides with anew design supplied by RadioWavz. RadioWavz worked hard to get the needed parts to me to meet a scheduled crane date that was rained out. So I am rescheduled alter this month.

Here is a photo of the center post. Winston KC9FVR has been helping me put the antenna together.

Hexbeam Center Post

Now let’s start with one of the weeks distractions – trees falling down. Across the road is one of ours, which with some great help from Vern K9EME was moved off the roadway to wait cooler weather. Not only has it been raining but it has been in the high 80’s/mid-90’s this week. (31 to 36c)

Top of our tree that fell across the roadway. Most of the tree was off the road.

Adding a DX Engineering HEXXbeam Mk II

Had an opportunity to buy a DX Engineering HEXXbeam MkII from K0PJ, adding to my Hexbeam collection.

My thoughts were to carefully collapse the antenna and transport it collapsed to my Washington Island QTH.  Later I’ll run a bit of a shoot out between the SP7IDX and Radiowavz antennas.

I’ve included some of the wildlife at the QTH and a picture of the trenching (one is a future ham radio wire conduit):

Trenching. Hitting bedrock eliminated my temporary antenna pole.

Notice the animals digging up the yard – raccoons are doing the most damage, the foxes dig for burrowing critters, and the Sandhills make tent-stake like holes everywhere.

The deer are opportunists grazing on wild apples and other deer treats.

In putting in the undergrounds the plumber hit bedrock only a few inches down.   One pipe is a sanitary drain for the sump pump and rainwater that really should have always have been there, and the second is a conduit for feedlines, control cables and the like for part of my ham station.

I think the near the house yard will drain much better as there was a bedrock ridge that restricted sub surface drainage that he excavated through.

The bedrock is why he couldn’t put in the 6×6 treated post at the end of the conduit run.  I had intended to mount a rotor and a short mast as an interim location for this HEXXbeam.

Looks like I will either end up with a concrete filled barrel as a base, or have a heavy steel tripod type base made up.

Even on the barrel, rotated by hand the HEXXbeam is doing really well.

K9ZW Shacks Evolve – Proper Dummy Loads, Additional Metering, New Power Distribution, Specialized Headsets and more…

I knew that doing a new station build wasn’t for the faint of heart, and as usual I am loath to miss a chance for upgrading the home QTH station.

There have also been massive deliveries of the needed connectors and other parts – whew!  I am sure glad I’ve not seen the costs all tallied in one spot – ouch!

All in all the order and assemble is fun other than the bills.  Now in spring the read work begins!
