Grantville's long-distance signal path
The north-north-westward path from Grantville to Mt Dandenong is long, so the antenna's front-to-back ratio matters: it has to ignore reflections and noise from behind while pulling in a distant signal ahead. That is a property of good antenna design, not just size.

What lies between Grantville and Mt Dandenong
Between Grantville and Mt Dandenong lie Jam Jerrup, Rythdale, Officer, Selby, Sherbrooke and Sassafras. Any tall building, ridge or tree line along that 65 km line affects what your antenna receives.
The alternative, Mt Tassie, is 90 km away at 90° (east) — almost a different direction entirely, so the antenna can only favour one.
When we aim a Grantville antenna we start at 346° and then peak it on the meter, because reflections can make the best direction a few degrees off the map bearing.
Building for Grantville weather
Exposed Grantville roofs take sustained wind, so we use heavier masts, guy wires where the mast is tall, and clamps that will not rust. Every connector is weather-booted and every join sealed. For Grantville we usually recommend a high-gain VHF/UHF combination antenna on a mast that clears the ridge.
What usually goes wrong in Grantville
- Antennas turned by storm winds on exposed roofs
- Undersized antennas with no margin for weather
- Lightning-damaged masthead amplifiers

Grantville antenna questions
Where should a Grantville antenna point?
Usually toward Mt Dandenong, about 346° (north-north-west) and 65 km away, VHF with horizontal polarisation. Mt Tassie (90 km, UHF) is the alternative. We meter from the roof before deciding.
Do I need an amplifier this far out?
Sometimes. If the signal at the antenna is clean but low, a masthead amplifier helps. If it is noisy or the antenna is undersized, an amplifier makes it worse. We decide from the meter readings.
Can you look after a holiday home in Grantville?
Yes. We work with owners and property managers, send photos of the work, and quote at a fixed price before starting.
