Post-processing Reach M2 files with OPUS

I hadn’t really looked that hard for an antenna to replace the helical M2 antenna. For the first observation on my new M2, I simply taped the antenna to the top of the bi-pod mount and measured the ARP and also entered the phase L1 and L2 distances when creating a new antenna template in my PP software. For the price, I don’t think you can beat the M2 as a basic reference receiver, at least for me. We have JAVAD gear here and it’s a wondrous piece of equipment, but I’ve always wanted just a no-frills base receiver for short baselines (<1-2 miles). From my preliminary first use, I’m pretty pleased for the performance. I’m planning on rigging an antenna mount this weekend using some pvc pipe and caps (approx 2.5" dia and about 3" tall). I’ve envisioned in my brain that this would also enclose the receiver itself from the elements. I’ll post pics once it’s finished. I just can’t see spending $1K or more for an antenna for this receiver.
