Starting with antenna work

SM2LIY showed up on Sunday evening and was looking forward to trips out in the forrest to put up beverages. So far we have managed to get up 6 of the total of 8 planned beverages. These will give us a good coverage primary on 80 and 160m all around the world. Of course we were a bit limited into some directions because of the terrain. For example to south we could only put out about 200m since there is a powerline there, but that does not matter since we wanted a wide angle beverage to the south.

The beverages put out are:

Beverage, 580m long towards West Coast US (330 degrees)

Beverage, 550m long towards East Coast US (300 degrees)

Beverage, 320m long towards South America (260 degrees)

Beverage, 220m long towards EU/Africa (180 degrees)

Beverage, 320m long towards South East (120 degrees)

Beverage, 450m long towards Australia (80 degrees)

Left to put out are a 800m long beverage straight north and one which is about 700m towards Japan. Also we need to put feeders to them but that will need to wait until we have gotten the ordered RG-58 and when we have built more baluns.

I also started to mount the top 6el yagi for 20m which has got a 18.5m boom. I had to weld the boom support since it broke when we took the beam down and also one element was broken. All beams will get a new feeding system (hairpin) but we are awaiting the isolating clamps from OH Antenna limited. Tomorrow I will try to finish up the 6el for 20 (except the feeding) and start to assemble the 3el for 40m. This antenna is currently a 4el which will be reduced a bit in size and plan is to have a 3/3 stack instead of the single 4el yagi.

Here are some pictures:
