Antenna idea based on the Y Quad

Hi all,

Im thinking about an antenna project that will involve making a field day style Y quad antenna.

I would like to omit the gamma matches if i can.

my idea is to isolate the vertical and horizontal members at the front from the boom.
then feed them directly with coax like dipoles.

i guess i would use a 1:1 balun or some ferrite at the feedpoint or something.

the reflector would remain unchanged in design if possible.

here's a link to the Y quad assembly instructions: http://www.macoantennas.net/files/Y-Quad_2011.pdf

so, am i crazy or could this work and provide some decent forward gain?

Y quad is basically two delta loops if I am not mistaken.
2:1 balun or use 1/4 wl 75 ohm coax to make a matching transformer.
 
i believe you are referring to the V Quad.

The Y Quad is a horizontal and a vertical driven element on the front of a 6 foot boom, each individually fed and tuned with gamma matches.

at the back of the boom is a quad type reflector with a 117" per side square of wire oriented diagonally.

I just think that the driven elements can be isolated from the boom, and then direct fed with coax, which would be a great boon for me since this will be a portable antenna that will get put up and taken down repeatedly. (hopefully)

once you isolate the driven elements from the boom, the question becomes, does the boom have to be metallic at all?

hopefully someone in here with some experience in this area can lend some advice.

thanks to all for reading!

thanks for the clarification of Y vs V.
if you isolate the driven elements similar to the old PDL2 type of antennas.
you can direct feed them and adjust spacing from the reflector to get a decent impedance.
