I have a technical question about the antenna mount on a BC245xlt. I have found a window clip mount antenna base on ebay. The description states:

Use this mount by lowering car side window and placing over window edge. Then window closes trapping mount in the window slot. Beautiful finished, all black powder coated and plated. TNC female on this window clip mount accepts many cellular and data rubber flex antennas. Can be adapted to SMA female with an adapter sold separately. Includes 10 feet of premium US made RG-174 thin coaxial cable and black plated TNC male for the tranceiver or phone side. This item has many possible uses including external antenna holder for cellular broadband data cards, cell phones, ham radios etc. This is an inventory closeout, sold under cost. All sales are final.

What I need to know is if the standard antenna on the BC245xlt will fit on this adapter. At Radio Shack (in the past) I have been told that the mount is a "BNC" type. I emailed the seller and asked him. He stated he didn't know. It is ebay item number: 110116651561.

Many thanks,
Wayne

The BC245 is a BNC connector. This means you'd need an adapter for the antenna to your mount plus another from the cable to the radio since this is claimed to be a TNC antenna mount.

It's your call as to whether this would be worth the hassle. Also, as I recall RG174 is pretty lossy at 800 assuming you are concerned with 800Mhz reception. I'd have to look it up but a few feet is no big deal but I'm not so sure the gain in moving the antenna outside the car would be greater than the loss at the full 10 feet.

RG-174 attenuation is about 84db per 100M. So 10 feet would be about 2.5db.

A TNC connector is like a BNC but with a threads instead of "twist-lock."

Thank you both for your answers. If TNC to BNC adapters could be found, would the RG-174 cable support the frequencies in the scanner ranges? I have been told that this is more of a cell phone type cable and isn't tuned to the scanner frequencies. I would be using it somewhat in the 800mhz areas, but probably moreso in the 151.00-159.999 ranges. Maybe a little in the 400 range. I had a similar antenna years ago but it had RG-58 cable and BNC ends on it.

copper wire will transfer anything for you, as prior post stated your reception will vary. The signals in the area for trunk are very good so you can get a decent job by just placing your radio on the dash.

IMO all this work isnt worth it. Just buy the $9 mini 800mhz antenna mount antenna off ebay as well. has BNC about 10ft of mini coax and is a 800resonant antenna. stick it to your roof and you dont need to swear when you accidentally roll down the window on the freeway.

one antenna, cable and correct adapters and frequency

I have used these for years, even use them at home for base mounts.
