well, Holland Electronics doesn't have the product E233577 in their database, perhaps you could tell us about other mark on the cable ?

 

good it has M10 threads

 

as to 50 vs 75 Ohm impedance, it's a parameter of RF cable what circuits dictate

usually for home equipment everything is 75 Ohm, professional - 50 Ohm

Well, the Hopper Remote Antenna Extender arrived today.  I was pleasantly surprised to find that it had the correct M10 (or whatever they are) connectors on the ends of the cable.  It had a male connector on one end and a female connector on the other.  The package was labeled with P/N 169178.  

 

The only problem for me now is that the cable isn't long enough to extend to where I need it to go.  I'm considering cutting the cable and putting standard F connectors on so that I can extend the "extender" cable using my existing rg6 coax runs.  The concern I have with that is I have read that rg6 is 75 ohm cable and I believe the RF signal calls for 50 ohm cable.  Is this correct?  I am not sure what type of cable the Hopper Remote Antenna Extender uses.  The only label on it says "E233577 Holland Electronics".  It looks similar to rg6, but I'm not an expert on this stuff.

I would assume that's 50 ohm cable and introducing 75 ohm in the middle is going to cause some mismatch (loss) plus the F connectors and a couple of barrels will be more loss.  That being said if I needed to extend the antenna location that is exactly what I would try.   The worst that can happen is a loss of $10.  :-)     However, I'm not telling you to do that, just what I would try!  :-)

based on google search e233577 is a 75 ohm cable

I just got the cable... same markings as above.

 

Length is 8-10 feet.

 

I forgot to measure it before I installed it.
