Anyone know the physical construction of the remote antennas?

Essentially there's two ways to do it - feed from the end or feed from the middle.
It'd be cool if they were a true dipole fed from the middle.
I tried to get some of the local guys who've installed boosters to donate their old ones in the interest of science but no takers

I went through Navy Electronics Tech school about 56 years ago, so please forgive dated and sometimes flawed memory.

The remote uses a phased array consisting of two monopole antennas. Normally a monopole will have a doughnut shaped radiation pattern, but the phased array gives a stronger lobe in the forward and rear direction in this case. Since a full wavelength at 2.4 GHz is 4.9 inches and the antenna on my Smart Controller looks to be 3" (on the outside, the radiating element inside is probably a bit shorter) so figure it's a half wave, at 5.5 GHz that would be a full wave with no need for a ground plane in either case. This is all just speculation . . . as that school was long ago and my Navy job was fixing high power radio transmitters and crypto code equipment - later teaching the latter.

Not sure why you'd think phased array - totally not applicable to these units.
Basically I'm asking about the physical layout - reason being a yagi works best when driven from the middle.

The driven element of a Yagi is actually a dipole the directors and reflectors shape the beam.

Yes I know. Thus the question. If it's end driven it's a simple monopole antenna. Center fed it's a dipole.
A yagi has elements that act as a reflector into director elements.
It would be nice if someone could actually answer the question instead of trying to second guess it.
The question comes about because there's a 3D printed slip on yagi array which has potential to outperform the parabolic units so prevalent.
But it will not be near as effective if the stock antenna is a monopole driven from the end.

You can also look at various repair blog articles or videos and maybe find one where the cable snapped. Honestly, I doubt that there are full dipoles in those as they are tiny. Like in any other cheap Wifi ones maybe a 1/2 dipole like the ones below called rubber ducky.
