TNC to BNC....or just replace?

[natiep]

Hello Everyone!

I just received this antenna which I bought from ebay to use with my PRO-197 scanner on the 850MHz digital frequencies:

It comes with a TNC male connector. Can I buy a TNC male to BNC male to connect it to my scanner, or should I just cut the TNC male connector off and just attach a BNC connector?

Thank you for your help and comments.

i would cut it off and replace the connector.

as a side note, you can pop the threaded collar off the TNC and *poof* you now have a universal plug in male connector that will fit N/TNC/BNC.

... that won't stay plugged in.

sure it will, so long as nothing pulls on it. they are great for quick connects while testing, though certainly for extended use you want the proper connector for a solid connection.

i would leave the TNC they work till around 3ghz with not much loss the last time i looked but i could be worng

At 850 mHz you do not want any coax adapters in the antenna line, period.

Below 1 GHz, even mediocre grade adapters have less than 0.1 db loss per adapter. I got curious about the frequent claims about how bad they are, so I measured a bunch. Adding a TNC to BNC adapter is absolutely insignificant at 1000 MHz or below.

Thank you all for your help and comments!

The markings on the cable are: 5D-FB coaxial cable. Can I crimp on an RG6 F connector to this cable?

 

[davidgcet]

why would you want a F connector if you need BNC? if the center conductor is stranded, you can't use an F anyway, as it uses the solid center conductor as the center pin.

I've never heard of a 'TNC' connector. What is it?

basically it is a BNC with threads instead of the twist lock.
