Long Wire Antenna Installation

A Wire, Trees and Chimney Pots
(Or how to string a wire to a swaying tree with lots of help from Friends.) by David Ferrington, M0XDF

How and When did this start.

• Started at the club back in November 2003
• Discussions lead to suggestions of the BIG tree.
• Bill, G0NWB suggesting I use some form of counter weight to keep the wire taught.
• Exploratory work by G3NCN Wire Services showed that the little tree was a better bet.
• Then I got a tree climber to get the wire higher.

Empirical Measurements

• Showed that tree could move approx. 2 metres
• But normally only 1 metre – all the time
• The tuner worked well, tuning 160m through to 6m ok.
• RFI wasn’t noticed on 10W

What’s Next?

• Move the Tuner to the Tree to try to stop RFI
• Work on the wire length for better match
• Put the doublet up
• Use it more!
