An antenna isn't going to "load down" a transmitter (assuming its properly designed and constructed as commercially built antenna would be).

If your radio puts out 10 mW, then you get an effective radiated power of 630 mW (an 18 dB gain). If your radio puts out 100 mW, then you get an effective radiated power of 6.3 W (an 18 dB gain). If your radio puts out 10,000 Watts, then you get a citation.

don't forget, at these microwave freqs, that the feedline also has loss, and it's length is a real concern...

True...I just didn't want to confuse the explanation with too many numbers.
