[TowerTalk] 80M antenna wire size

[David Gilbert]

According to EZNEC+, an 80m dipole at 100 feet (resonant and matched at 
3.7 MHz) has a 2:1 SWR bandwidth from 3.55 MHz to 3.87 MHz with #10 
copper wire and from 3.57 MHz to 3.86 MHz with #18 copper wire. Much 
thicker conductors or similar conductors at higher frequencies would 
make more difference of course (I've modeled 12 inch diameter wire cages 
for 80m and they make a usable improvement in bandwidth), but in spite 
of what somebody just posted the advantage for #10 wire on 80m does not 
seem significant to me for bandwidth.
