That AR10 is an integrated antenna, likely not passing over your wires or split.
Your spectrum analyzer is likely too slow to be measuring signals. The entire band should be saturated. R/C systems will use the entire band from 2.405GHz to 2480GHz.
Power means very little when it comes to communications. Every 6dB of receiver sensitivity doubles the effective range, but it takes 4 times the output power to double the effective range. XPS receivers are extremely sensitive, and have excellent noise rejection (besides the normal rejection that spread spectrum offers). All XPS RF modules output the same power. Make sure that your antenna is not cross-threaded as that can significantly reduce the output power (partial shorting of the antenna).
The Nanos are full range, but the RFU receivers have even higher sensitivity, so their range is longer. The antennas should be located 90 degrees from each other for the best possible reception. Those are two separate antennas, which provides spacial diversity.
The XDP has not been available for about 8 years. You can make an XDP by using our Serial Link (used for expander products) with a Nano receiver. The Serial Link was also discontinued by our supplier a few years after the XDP.
