50MHz, 144MHz and 432MHz Gain and G/T Simulations by VE7BQH

Updated regularly

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).

Download the G/T tables as Excel spreadsheets
You can then sort and display the data that you want to see.
