[Moon-net] VHF Antenna Noisetemperature by YU1AW..

[Paul Chominski]

To All,
12 years ago I've got dramatic improvement of performance modifying old 19 
el CC yagi for 144 MHz according to VE7BQH Lionel's design. Few years ago 
when I was experimenting with extension of my dual-dipole feed for 70 cm, 
I've got again help with noise temperature simulations and suggestions what 
to do from Lionel. Thanks to him I could improve my first version.
I think, there is a essential practical value in Lionel's work.
