I intend for this to be a general/conceptual question that could apply to any wireless communication hardware, however I will use a specific example to talk about.
Let's consider the nRF24L01. (Datasheet).

As shown above, the standard module uses a PCB antenna.
There is also a version that uses a screw-on omnidirecitonal antenna (AKA "whip"):

Let's say that a pair of PCB-antenna transceivers give a usable range of 10 meters.
Let's also assume a pair of whip antenna transceivers exhibit better range. (The common consensus I've read is that there is a noticeable improvement. Let's say it results in a range of 20 meters).
My question is about having a mixed pair of antennas for half-duplex (single direction) communication. What if one were the PCB antenna, and the other were the whip antenna... Which transceiver (transmitter vs receiver) should use which antenna? Would it even matter?
I'm interested from both a theoretical and practical standpoint, as they are often different. One extra variable I can think of is the orientation of the antennas.
I'm also open to alternate title suggestions from someone who knows better terminology.
