I am hooking up my Grand Rapids Technology ADS-B hardware and two of 

the connections are coax.  I asked and they said either RG58 or RG400 

works.

1.  Should I use one or the other for some reason?

2.  I can't thread a completed coax where it goes with connectors so I 

need to fasten or crimp them on afterwards.  Anyone using a tool 

available at Lowe's or HD or Fry's or ...?

3.  I went to Lowe's and didn't see any RG58 wire or connectors.  I saw 

they had RG59 whatever that is.  I did see RG58 A/U at Aircraft Spruce.



Hints appreciated.  Thank you.   JBB

Crimp tool: 

http://www.steinair.com/product/ratcheting-crimper-frame-only/  and 

http://www.steinair.com/product/bnc-crimp-die-only/

Do not try to use TV or automotive crimpers.

If your run is about 6 ft or less, you can use RG58 of the stranded wire 

center conductor variety. I suggest RG-400 for your transponder/ADS-B 

Out transmitter. RG-58 will do the job for the ADS-B In receiver, as 

well as for your com radio(s).

RG-58 and RG-400 are 50 ohm impedance, which you want. RG-59 is 75 ohm 

impedance and usually solid core center conductor.

RG59 is 75 Ohm coax,           used in video/tv applications. RG400 is higher spec 50 ohm           coax. RG58 is the more common. For short runs, RG58 is           normally adequate.

If you have your cable lengths….just call Stein and have him make the cables with RG400.  If time is money, it is the best way to go.

 

If they have to be made in place…..

 

I used RG400…..
