If you are staying in the outback away from civilization, an outdoor antenna may be required to pick up and transmit stronger signals. Ensure you place it in a clear area on high ground for maximum effect. Within city limits, an indoor antenna is a good alternative to avoid a sore thumb in your garden. Normally attached to the highest part of the house, insulated wire is run from the antenna to the radio. There is no hard and fast rule on which antenna heights work best. It all comes down to testing and tuning for what best suits your environment.
