Which coax pigtail to choose for RC controller

[GravityRZ]

i am in the process of installing external antenna's on my rc controller.

i have both RG178 and 1.13 coax pigtails available.

which one should i choose?

1.13 is way easier to use and the u.fl connector will probably stay in place.

RG178 is a bit thicker, should have less DB loss but there is a risk that the u.fl connector will come off when twisting the cable(when reassembling)

also i read comparison between RG178 and 1.13 and there they state that the RG178 has more resistance(but less DB loss) strange because it is a thicker cable

i am puzzled, please advise.

cable is 15cm long

I may be able to help but first.
1. What Controller?
2. Why.
3. To control which drone?

Ok,
since there is nobody willing to help me i do what i always do(answer my own question)

here is the answer, hopefully this will help other people.

i compared specs
on 2.5 ghz the 1.13 gives an extra loss of 1.81% compared to RG178
on 6 ghz the 1.13 gives an extra loss of 1.18% compared to RG178

so it is safe to say the difference is minimal on 15cm cable
with 1.13 you get the advantage of cable flexibility and a guarantee that the connector will not come loose(you just can not twist the cable enuogh to make it pop off)

		30,48cm
	freq	DB/feet	percentage signal	percentage signal bij 15cm	difference

Good info, thanks. I was just wondering the same thing when looking at cables.
