Hello All !
Saw the thread today so thougth i drop in 
)
What i think so far...and perhaps already mentioned by some its a long thread already..
One could call it a co-linear since there are two current points on the antenna.
Futhermore the radials are there for the biggest part to profide a normal ohm value one wich we could adjust with a gamma-match.
If we would forget the radials and ring the impedance would be very Capacitive -J.
The Gain however more or less remains (+/- 0,5dB). (high angle)
The best thing wich comes along with attaching radials is a lower radiation angle.
The 3/4 wave in this case has got a nice low lob and a second lob a bit higher.
Actually it would be great for real dx through F2 and do a good job in with the sproadic E season aswell.
No big mistery..in general radials lower angle and do that for every 1/4 wave (5/8,3/4 etc)
Now...the biggest worrie i have so far is the gain that one can reach (+/-4,2 dBI ) is with a very thin radiator...that migth be the explination why the antennas are always brougth on the market a bit too thin to everyones believe.... ( not a fact!)
each time i enlarge the main radiater gain drops rappidly towards 2 dBi
Intresting antenna so far !
Kindest regards,
Henry
