We decide the off-grid hytte cabin needs a shortwave antenna and inside hookup.
Visiting amateur radio enthusiasts can easily connect their stuff and "work the world"
Two 100 W Solar Panels and a pair of deep cycle marine batteries are plenty to keep the cabin comfortable
 

Here's tree-climber friend Blaine setting a pulley at 40 feet on one tree

We build a 66 foot dipole antenna for the forty meter ham band
more about why we chose 40 meters

This is a home-made transformer called a balun that has to be in the middle.
The two 33 foot legs must be measured with in 1/2" for the antenna to work correctly.
 

Here's dog Sage observing the final antenna wire hookup at the balun
Soldering with a generator

Antenna wires are nearly invisible
Note the balun at 40 feet and nearly invisible coax cable to the corner of the hytte cabin
 

We had an extra box in the wall from an earlier wiring setup

Drilling a plate for the wall connection
 

Using a long drill to bring the antenna cable up inside the wall.

Setting up to install the connection plate
 

Convenient jacks for 12V power, ground and the antenna connection

Checkout and Testing
Voltmeter at top showing an acceptable DC reading from the power jacks.
Lower instrument analyzes the complete antenna system for proper frequency range and matching. The antenna went up and down four or five times as we trimmed it based on the readings from the analyzer. The "match" is most critical parameter when designing and installing an antenna such as this.

Here's friend Dan KA7GPP and his KX 2 Radio giving everything a good checkout.
It puts out ten watts and is the latest craze in high performance miniaturized radios.

A shot of Dan making the first contact on the new antenna.
He's having a Morse code contact with a guy on a mountaintop in Nevada!
We look up KJ7WGM on the phone/internet and read his bio.
 and his whole interest in the hobby is hiking to mountain tops and setting up a similar high tech battery powered radio
Some radio hobbyists have started a club called SOTA to explore the aspects of hiking to summits, climbing, portable radio equipment and mountains. Here's his internet log entry for our contact.
 

Guess it doesn't show much and its ready to go
