40m Aluminum Antenna tower.

My tower is a 40 meter crank up aluminum tower hand built in Finland. The tower has been up for just over 6 years and has never had any problem although it has taken several very substantial Lightning strikes in past years (weeks).

The antenns generally sits at 15-20 meters in height but I do crank it up on contest day or when there are good enough conditions to work 6 or 2 meter DX.

The rotor is aYaesu G1000DXC. The combination gives me about 300 kilogram which can easily be turned my the rotor. That could easily be increased with the addition of a bearing but I opted for a bushing because of the harse Finnish winters and my dislike for climbing towers too often.

Marketing crap :)

This tower is a result of many years of experience. The use of a unique rolling construction minimize the friction and discord between the movable sections. This gives a maximum lifetime of the tower. In spite of the rather complicated construction this type of tower is available in a kit form. Due to the special profiles used and the high precision in construction such a kit is rather easy to assemble as well as easy to handle thankts to the material - aluminium. When ordered as a kit all kind of transportational accidents are at a absolutely minimum. Even the freight cost will be very much lower than when assembled. In areas where transportation costs are difficult this telescopic tower may be well recommended in a kit form. Experience of mechanics is however recommended for a kit assembly.This telescopic tower is of course, available pre-assembled and the telescoping parts are contained and wired. The weight of a 15 metre telescoping tower is approximately 100kg's only. The tower consists of tower sections different in width and sinkable inside the lower sections. The top section is wide enough to house a rotator, even large one like the Yaesu G-2800 model. The top plate is equipped with a polyurethane bushing for the top tubing at a diametre of 50 mm's. The middle section has the same width as the Standard Vargarda Mast. The lower section is approximately 50 cm's wide like the fold base. Each section has attachments for guying wires wich are recommended to be used to secure the tower when erected in a windy area.
