goodday all
was having a look at terlin aerials today and learnt something new when winding the wire along the aerial to bridge out the 2 points the bridging wire should be wound clockwise
dont know why but thats what they say

Hi Steve, Might be something to do with the earth's gravitational pull in the southern hemisphere. I don't know if you have noticed but water goes down the plug hole clockways and cyclones go round clockways.
If you were in the northern hemisphere they would have probably told you to wind it on anti clockways as the water goes down the plughole anit clockways and hurricans go round anti clockways. Only a theory on my part.

Called the coriolis effect.

Interesting thing............ the big weapon tower they built in Canada, was built using the slip concrete pour method, and the re-enforcing cables had to be pre stressed prior to the constant pours, to counteract the pull on the earths rotation!

Still don't know squat about your ariel though.......

Hello steve, did they say to wind the wire clockwise from the bottem of the antenna or from the top of the antenna. I have also been told told that when you change the positions of the wire, not to have the wire loose, must wind wire nice & snug around the mast for best results!
Where are you going for the next big trip?

Carazy.

How about the antenna wire being wound one way makes a magnetic field - tap wire wound the other way makes opposite magetic field - one tends to cancel the other out .... Is that a theory or what ?
