Why coastal antennas fail early in Portsea
Wind is the other coastal factor in Portsea. Exposed roofs take the full force of storms off the water, and a mast clamp that has rusted will let the antenna rotate a few degrees at a time. A slight turn away from Mt Dandenong is enough to cause dropouts on the weakest channels.

What lies between Portsea and Mt Dandenong
Between Portsea and Mt Dandenong lie Aspendale, Waterways, Noble Park, Rowville and Ferntree Gully. Any tall building, ridge or tree line along that 77 km line affects what your antenna receives.
When we aim a Portsea antenna we start at 46° and then peak it on the meter, because reflections can make the best direction a few degrees off the map bearing.

Portsea antenna questions
Which transmitter should a Portsea antenna use?
Mt Dandenong, 77 km away at about 46° (north-east), VHF with horizontal polarisation.
How do I know if my antenna is corroded?
White powder on the elements, green or black staining at the balun, and cable that is stiff or cracked near the antenna. Reception that fails after rain is another sign.
How often should a coastal antenna be checked?
If you are close to the water, a quick check every few years catches corrosion before it fails.
