No, put the rx out to that pole, then extend the low frequency cables (AV, power gnd).
Basically using a patch - and I assume it's a linear polarized one - is not the optimal solution on 5.8Ghz. Way too many reflections. Use an SPW antenna on the ground and a cloverleaf on the plane. This will result in bigger range than what's flyable with the patch. If you want more range, use a circular polarized directional antenna on the ground but based on your questions, I'm almost 100% certain that a pair of CL and SPW will give you enough fun for the upcoming year.
