You are missing that the DS-16 provides RF signal distribution equivalent to both sides left and right of the Tx while for the DS-12 this is not the case. RF signal distribution/quality to the right side suffers because it's partially blocked by the electronic installation. This is what Jeti users found when flying same model with same receiver and same antenna installation and comparing their DS-16 log with DS-12 log. And ofcourse Jeti and Jeti dealers simply ignore and disagree with that findings.

Well the 16 is redundant right? Where the 12 only has the one 2.4 module. Can’t really compare the 2 fairly in my opinion.

Agree. Two different setups so one cannot expect the same signal distribution.

Just saving maybe 50 bucks for a second RF module, is it that what Jeti customers want and what they were waiting for?

You are paying minimum 600 bucks up to 1k for this Tx and you are willing to accept bad signal distribution/quality to some extent?? And your solution for that technical deficiency obviously is just lowering the signal warning tresh hold, meaning decrease of safety margin!! My respect, I would not, but for sure Jeti will love such customers.

Have there been range issues with the DS-12? I have not read of any on various sites so not sure why the dismay other than you feel there should be redundant antennas.

Do you feel the single antenna can be better placed in the transmitter housing?

I have one of the DS12 transmitters and it has been working just fine for me. I am limited to 300 feet because our club flying field is within the controlled airspace of a major airport in the area. But range hasn't been a problem, even when I fly the planes way out horizontally for turn arounds etc. I did change out the SD switch for a two position switch instead of the momentary contact spring loaded switch. My other brand radios all use a regular switch in that position on the TXs too. I use it as a throttle cut on my helicopters and airplanes.

A Torx T6 screwdriver was needed for the little Torx screws holding the back of the case on. Plus you need the special switch nut driver tool for their special switch nuts too.

My only concern is the back of the case feels slippery in my hands. I am always thinking it is going to slip out of my hands in a moment of inattention. It is a bit more worrisome when you hand launch a plane. Some kind of a non-slip surface on the back for the fingers would be a big plus.

Look at the DS 12 thread here, Jason and others have posted what the use for anti slip .

In the DS-12 is the horizontal antenna the 900 or 2.4? I understand the point you are making but I just do not see it as a problem for how I fly. I have spent some time looking across the inter-web and really have found only one complaint about the DS-12 and the issue was found to be how the user was placing his receiver in the plane. Nothing to do with the DS-12.

I suppose one could 3D print a antenna housing, get a longer 2.4 antenna, mount the new antenna housing on the top and back of the LCD area and then thread the new antenna up it.

However, for my flying I think the present arrangement will be fine. I suppose redundant antenna would be great in noisy areas or for those that want to fly 2 miles away. My area is pretty quite, electrically and 2.4, and at my age and eyesight nothing gets more than a few hundred yards away.

The 2.4 antennas are the two in the upper right corner 90 degrees to one another. The 900 antenna is the coil below them.

Oh crap ... OK, now I see. So the big complaint is that there is only one RF deck. I am just not seeing where the big problem is here then, if I wanted two RF decks then I would have bought another model.

Frankly, I am extremely happy with the DS-12 and signal. No problems at all. I expect that if JETI felt there was an issue they would have used 2 RF decks.

I took a another look in this thread and didn't see any mention about it. The other long running thread in this category is over 2000 pages long and a search of it didn't provide me wtih any hits.b But I was thinking about using some of the "no slip tape' from our Home Depot or Lowes stores. Granted you wind up with a roll of the stuff, but I can use it on other things too. They have several different types, so I need to go and check the different tapes out at the store before I buy one.
