Circular Dipole the polarity of the circular dipole is important. Copper Center feed to the Right Hand terminal. The insulator with terminals goes at the top of the aerial, and the cable runs down away from the top of the aerial. otherwise it will eventually fill with water and corrode the connections. (remember to thread the insulator cap over the cable before connecting the cable to the terminals)

Wall Brackets T+K Fitting to a Wall requires T and K wall brackets, the stand off must allow at least 1 centimeter from any guttering or tiles otherwise in windy weather the mast vibration will keep you awake knocking on the building. Although often pictured or even fitted the wrong way round. The top bracket must be the stronger one i.e the three legged K bracket with three heavy duty steel rawl bolts is always at the Top. see below example. However remember that a chimney or gable end mounting is preferable as it will often provide much more height and hence signal even with only a short mast. cable length, and so a proportional signal loss, may be increased, but this will usually be irrelevant compared to the extra gain in signal level and quality provided by those extra feet in height.

Chimney Double Lashing Double chimney brackets must be used with all Galaxie aerials due to windload, even on a short chimney they will be much stronger and more stable. Never use T+K brackets on chimneys as they are usually built of just a single skin of bricks and are exposed to fumes and the weather. Because of this inherent structural weakness the wall brackets may actually pull the bricks out of the chimney, whereas a lashing bracket can actually help hold the chimney together.

Fixing the wire The wire must be tied correctly or it will slip and fail. a locking loop must be wound as in the photo below. Never over tension the wire as it may snap or worse sill crush the chimney.

Through roof fixing If all else fails a through roof fixing can be the answer. Very strong but limited to a single mast. Remember to seal the top of the mast or your loft will fill with water.

Through roof interior The loft space provides many possible fixing points, however this work is best done on a cold day, it gets hot up there.
