I have a signal transmitter that needs wiring. My problem is that, the antenna has a type N jack and the lightning surge arrester has a type TNC jack.
The question is, if I buy ends for this? Will a RG6 coaxial work for both ends or do have to get a adapter? If not, what will?
 
what is the device you are connecting? Is it 75ohm? Is the DB loss of RG6 acceptable for the application?

It's 50 ohms. The db loss is next to nothing. The cable only needs to be 8' max in length

well if its 50 ohms, dont use RG6.

What is the device? Is it wireless network gear or something else? Ususally with the wireless network stuff you have to use LMR400 unless its a 1 or 2 foor pigtail.

It,s for a cable guided ferry. A small 900MHz FR transmitter sends a signal to a receiver that sits near the waters edge and tell cable motor to tighten or loosen the cable.
 
RG-6 is 75-ohm, and your system is 50-ohm. More than likely being low powered and short distance will work, but you are significantly reducing the performance of both the transmitter and reciever.

What I would be worried about is if the system fails at some point and there is property damage or injury as a result, if discovered you used the wrong cable you could be held liable.

FWIW there a quite a few companies that can make you a cable in any length with any fittings you need like PASTERNACK. They charge a fair amount for thier product but it is a heck of a lot cheaper than buying the tools and piece parts for a one-time project plus it comes tested to the highest standards.

I really don't understand what you are getting at. If you are willing to put together the cable yourself (and it's CONNECTORS not ends. That right there may explain a lot.) then why don't you just purchase a length of RG-58 and do it right? You can even get RG-58 with factory connectors, usually BNCs or UHFs. I think even Radio Shack has that. It's then a simple matter to find adapers as has been noted.

You know, there actually are other cables besides RG-6 and CAT5...

Pasternack is exactly where I purchased a similar coupling TNC to N. Good site and got it the next day.

It's not that I was trying to do it cheap or fast, It was a job that was dumped into my lap. Coaxial or signal cables is not my specialty. Today I had to do a self crash coarse on connector (style and types). While keeping 6 other men busy working and doing layouts. But I'm always eager to learn something new. So if RG58 is what should used, then that's what I will use. THANKS hbiss

you need to see what type of cable the equipment specs calls for. RG58 isnt good for alot of things.

YUK!! will then: My first first job is talk to engineering to get their specs on the transmitter. Who would guess trying to finding 6' of missing coax would be so complex.

in reality, it would probably even work fine with the piece of RG6

BUT

RF people are worse than computer people who think their network cables are too close to the flourescents, audio guys who want nothing grounded, and housewives making you hold a 40lb chandelier up for 20 min while they have you move it up and down an inch all combined. When they have some sort of problem with this thing its going to be all your fault for not using the right cable.

Then again, the mfgr might call for RG58. I wouldnt guess on this though.

The manufacturer probably can supply the cable with connectors. Did you look? I agree that RG-58 may not be what they use but if it's 50 ohm and for 6 feet it won't make any difference.

it may make a difference depending on how much loss budget there is. RG58 is pretty lossy at 900mhz, add in a pair of field installed connectors and it might be a problem.

At 6-feet doesn't make significant difference if it is RG-58 or RG-174. If it were 50 feet or more, then it makes a difference, but at this length, nah.

at 900mhz RG58 can lose as much as .165db per foot, so 6 feet of cable and a couple connectors on it the loss *could* matter. LMR400 only loses .039db/ft at 900mhz. My only experience on this is wireless lan setups, and i know RG174 is used for short pigtails of a couple feet, anything more than that LMR400 is used.
