KONG37 - The Antennas

 A bit more about our antennas:
In Kongsfjord, we have four antenna paths with five antennas:
- 500 meters, 50 degrees.
- 570 meters, 80 degrees.
- 275 meters, 310 degrees.
- 2 x 340 meters, 340 degrees.

We also have a temporary setup at Mount Loran: 1000 meters, 306 degrees.

Average height is 120 cm, except the 310 which is 200 cm. Various types of support are used. Below are three types:

- Impregnated fence poles. More durable than fiberglass, and my chosen material for supports on my property, where stealthiness is not an issue.
- Fence poles with added weight. Needed where the ground is rocky or where two antennas meet.
- Fiberglass poles. They are quite durable and flexible, and not least quite stealthy

The 310 beverage has very sturdy, long fiberglass poles which are supported by impregnated fence poles.

Nothing lasts forever though. Around 5 % of the poles need replacement every year. The antenna wires, although exceptionally solid, need replacement every 4-5 years, sometimes more often. The winter is unforgiving.
