[UK-CONTEST] Aerial Mounting?

[Chris Tran GM3WOJ]

Hi Tony

I have two HyGain 205CAS antennas here - by far the easiest method of 
installation is to mount the boom on the stub-mast, with the boom parallel 
to the ground i.e. horizontal, with the boom at a convenient working height 
e.g 5'.   Mount the boom to element clamps on the boom.

The upper halves of each of the 5 elements are fully assembled and mounted 
on the upper side of the boom, along with the bracing wire, coax + balun - 
then the tower is progressively tilted upwards, adding the lower half 
elements in sections, tightening each section as you go.

Eventually the antenna is fully assembled, with the tower still tilted over 
at about 45 degrees.

Don't waste time/money on any sort of swivelling clamp system - the above 
method is well proven with all yagi antennas where the elements can be 
broken down into short sections - rivetted antennas like Force12 are another 
matter.
