Cable adapter treasure hunt BNC-F

[fuzzymoto]

Juts trying to tidy up my desktop a little and lower the big whip of coax sticking up from my portable. I'm searching for:

A BNC-Mail 90-degree to F-Type Female


I have the regular (non 90-degree) but can't find the 90-degree. Here's the puzzle. Hopefully someone can fill in the missing gap....and crimp on's are out. I can never get a connector on cleanly for my TV so I don't want to even try.

My antenna coax terminates with an F-Type Male
My scanner is an SMA-Male (Uniden BR330T)
I need to connect the two and get a 90-degree bend in there with as few adapters as possible.

Currently I have the Uniden SMA-BNC adapter, then a BNC-F-type adapter to the coax....but no 90-degree. I can easily find a BNC-BNC 90 but that adds one more adapter. If I can find a BNC-F-type 90-degree that would be great or even better yet an SMA female to F-Type female 90-degree (which cannot possibly exist even in a patch cable).

Any suggestions or links would be great!

Thanks

you may try getting a short jumper of coax with the F on one end the SMA on the other. I have never seen a 90 degree like you describe.

I looked for the cable too...both ends are female so I don't think a cable can end in either a female F-type or female-SMA or both. I could end a coax in a male F-type and do an F-type female-female barrel adapter but that adds a 3rd adapter and a coax.

I can solve the puzzle already with 3-adapters:
SMA-female to BNC-female
BNC-Male 90-degree to BNC-female
BNC-Male to F-Type female

Wht not use a BNC T connector that has 1 male and 2 female - and then F to female BNC?

 

[fuzzymoto]

Actually that will still take 3 adapters to get to the the SMA connector on the scanner itself (same as using the solution I outlined in post # 3 above only using a BNC T instead of BNC 90. Still an unsolvable puzzle?

Even something as simple as the Radio Shack 278-221 will do the right angle part. As far as right angle and F-to-SMA in the same piece, I don't think anyone makes an F-to-SMA at all, straight or right angle. I wouldn't use a T connector for a few reasons - there's an unterminated stub that's long enough to matter at 900 MHz, there's a piece sticking out (it can get in the way, it can catch on something ...) and a good BNC T is a lot heavier than a good F right angle.

 

[fuzzymoto]

Thanks. I guess we're still at the 3-connector setup. I was hoping there would ba a 90-degree BNC-Mail to F-Type female. They do make a non 90-degree of that one. If I have to do 3 connectors then I'd probably just use a BNC 90-degree unless there is some advabtage doing the 90-degree in the F-type instead.

Anyone with a solution that takes less than 3 adapters????

Changing the F plug on your antenna cable to a BNC plug.

This is what I would do in your situation. I say, the lower the number of adapters used, the better.

Changing the F plug on your antenna cable to a BNC plug.

Better yet, change it to an SMA Right Angle! Although he did say his termination skills are lacking...

 

[fuzzymoto]

Very lacking. The only reason I chose to run this cable up to my attic is because it already had connectors on it. Otherwise I would have run a cable with SM on one end and PL on the other.

I've never seen "twist-on" SMA plugs, which is why I recommended the BNCs. Granted the twist-on plugs aren't as good as the crimp/clamp styles, but they do work well, and are fairly easy to work with.

All you would need is a coax stripper, a fairly nice one can be had at RS for about $12, IIRC.

 

[fuzzymoto]

Yes....I've thought about re-terminating the coax. Only problem is that if it does not work out I'm left with a connector-less coax. Believe me I've had many TV connectors fail, as simple as they are.

After about 2 years, a twist-on connector at 850 MHz is about as good as imaginary cable - the loss is close to infinite. (You need gas-tight connections, and twist-on connectors are about as far from gas-tight as you can get without not connecting the wire at all.)

Hi all,

Are we getting so fuzzy(moto) we're overlooking the obvious? KISS

 

[fuzzymoto]

And just how DO I keep it simple?

 

[fuzzymoto]

I guess it's either new connectors or a custom patch cable of some sort....?

maybe this will help

Close....if it was only F-Type instead of SMA to SMA but it does get the 90-degree in.

Why not use 50 ohm cable like RG58, RG8X, LMR240, etc? You can get just about any connector you want for them.

Because the other cable was free and is already in place..
