I'm trying to track down a SMA adaptor for a 396t/330t. There are numerous ones available via Google search, but all have the skinny "nut" type base and not the large knurling like the SMA adaptor that comes with the radio.

Uniden has them listed, but they've been back ordered for months.

Anyone have a linky to a good SMA-BNC adaptor? TIA.

I use the one from Universal Radio. Look for "BNCJ-SMAP" (Order #0292):

IIRC the 396 came with a sma-bnc adapter.
The one that came with the 396 is a design somewhat similar to the unit from Universal-radio.
It is very strong and I beleived it is designed for the 396.
Uniden may sell them have a look there or get this one

it is #0292

I wondered the same thing. the Universal-radio version (which looks identical) is also all black. Is it actually paint? It looks to be to be some sort of surface treatment almost like anodizing.
Clearly it is important to have a clear path for the center conductor. The outer part of the connector I assume is ground. I have a feeling that that paint of finish whatever it is has the potiential to raise the RF Impedance of the antenna. making it less effective.
Is this a possible negative effect?

For yaesumofo and slicerwizard, I think you mean the coating is conductive not non-conductive. There are lots of antenna connectors around that use an anodized black coating and it is thoroughly conductive and should not change impedance values appreciately.

Based on the pictures it does not appear the inside is coated, where I bevieve the ground connection is also made.
I assume you meant the BNC part; BNC connectors ground (shield actually) is on the outside of connector (where the lugs are).

My guess is the black coating is black zinc plating, which is conductive. Unless the connector is aluminum, it wouldn't be anodized.

The bayonet part is part of the ground but the actual "ground or shield conductor" is the fins surrounding the white insulator on the male, which makes contact on the internal part of the female connector. Somewhat protected from the elements. These SMA adaptors are not coated internally so there is a ground no matter what you coat the outside with.
