Congratulations on your ticket.
I would try a 2 element to start with, they are cheap and easy to make and it will give you experience with a 3 dimensional antenna! I have built a couple of 10m 2 element quads in the past, I used a 4 foot 6" length of aluminium tubing for the boom, 3/4" tubes about 18" long in the form of an "X" at each end of the boom and bamboo garden canes for the spreaders. OK so the spreaders won't last, but it costs little and is easy to make, it will be a good experience too.
You can bolt the 3/4" aluminium tubes to the boom with with "U" bolts, or even TV aerial fixing clamps, the canes do not need much to secure them.
There are feed arrangements for a 2 element 6m quad on my web site (www.astromag.co.uk/quad
), obviously you would need to scale up the 75 Ohm matching section from 6m to 10m. To save you working out dimensions for a 10m quad, an upscaled version for 28.5 MHz would be sized as below (from EZNec 4):
Driven element: 104.2" each side
Reflector: 110.9" each side
Wire: 16g enamelled copper wire, or bare copper wire (not PVC insulated).
Feed impedance: 100 Ohm (use approx 68.6" of RG59 coax for a quarter wave matching network to 50 Ohm, check with an analyser if you have access to one).
SWR: 1.03:1 at 28.5 MHz, gain in free space 7.25 dBi, Front to back 23 dB
