[Antennas] Quad Question

[Tom Horton]

That is one of the ongoing debates... I never have grounded them or even opened the braid and I have always had fantastic results. 
NOW that does not mean it wouldn't work better with some other arrangement but how much better is the question.

According to LB Cebik, they should be opened.  Practically he said to 
feed them with a 1/4 wavelength (electrical) of coax and open th end 
(bot braid and center conductor disconnected) - leaving the braid 
grounded grounds the loop.  I built a 6 band version on a Gem Quad 
Spyder frame and it works great! Used DPDT relays for each band and 
wired them to open both sides of the coax when de-energized.
