Split the twin leads of 2 rolls (not practicle at 250
feet). It’s better to buy 4 rolls.

Best Way to Climb the Poles?

The alternatives to American climbing spikes
was a big surprise for me.

CLIMBING SPIKESDon’t use traditional American climbing spikes. They damage the surface of the wooden utility pole. But, on the other hand, when the diameter of a “tree” is too large you will have no choice but to use climbing spikes. This post is limited to wooden utility poles used for amateur radio antennas. Wooden poles are the poor man’s alternative to amateur radio antenna towers. I need a method to climb tall poles without using the destructive traditional American climbing spikes.

I found three alternative methods.

(1) The Mumbai, India Solution
(WORKS! BUT NOT GOOD ENOUGH)
MUMBAI INDIA SOLUTION1

I searched Google, Google Images, and YouTube videos for the best alternative method to climbing wooden poles. The most comfortable and cheapest method came from Mumbai, India. It appears to be made from bicycle parts.

(2) The Switzerland Solution (Too Expensive)

SWITZERLAND METHOD

This is Switzerland’s High Step Solution. For me? It is the High Dollar Solution because there is no way I can afford this system. But it appears to be the best corporate application.

(3) The Slovenian Solution (PERFECT SOLUTION)

SLOVENIA POLE CLIMBING SHOES

BEST OF THE BEST

The best solution is the Slovenian (next to Italy) Plemont Pole Climbing Company’s UNI‑W‑Standard Pole Climbing Shoes.

Plemont Pole Climbing Company
In Slovenia (Next to Italy)

The Plemont Company emailed their invoice to me. I will be ordering their shoes March 1st. Plemont’s invoice is on the next page with their brochure after that page.

The Next Stage
When I Can Afford It

Then, the next problem to solve is finding six, 40-foot utility poles. Then it’s finding an auger truck to drill the 6-foot holes in the ground and a Catepillar Bobcat Claw to plant the 6 poles. That’s going to be a huge problem to solve. But, I will have the Slovenian pole climbing shoes ready to climb those poles!

Another alternative method. Utility pole without the arms  for my purposes.


This JCB Pole Planter seems to be the best method to plant 6 poles in a hexagon pattern.

The Advantage to Using Critical Thinking and
Occam’s Razor is Finding Perfect Solutions.

Take nothing for granted.
Question everything.
Do your own research.
Think for yourself.
Arrive at your own solutions
without any influence from others.
From that, you find the right solutions!
