Bill, K4XS/KH7XS is wondering about a dipole reflector behind a quad driven
A quick Google search for quagi finds:
The VHF Quagi
from an article by Wayne Overbeck, K6YNB in QST April 1977
"Before the next West Coast VHF Conference, the ill-performing, store-bought
Yagi was modified in only one way. the driven element was removed and replaced
with a quad type loop of no. 12 wire. There was no matching of any kind. A
type-N connector was soldered in the center of the quad loop bottom side, and
it was fed directly with RG-8/U. Now the SWR and gain both looked better. In
the gain contest at the next VHF Conference, this antenna was measured at 9.8
dB over a dipole. Simply eliminating the gamma-matched dipole and adding a quad
loop had increased the gain 3.4 dB!!! "
Now, understand, this was done to a yagi for 432 mhz........... Still
Good luck with your project Bill.
