- G/T Simulations - by VE7BQH
- Here you will find information on how antennas behave when stacked
G/T is an important figure-of-merit for the antenna's overall receive performance, because it balances forward gain (G) against received thermal noise (T).

- Antenna Gain to ERP
- A radio's transmitting power can be concentrated along the horizon by use of a GAIN antenna. Although you may still be transmitting with four watts of power, your effective radiated powerwill be greatly increased. This table shows the effects of antenna gain on a transmitter with 4 watts of transmit power.
