Gd Afternoon Everyone, I'm closing in on finalizing the feeder wires to my first level and while in the planning stage I started to wonder when I relocate my Cab-2 base will the signal strength diminish due to its location underneath the table.  Is there a antenna extension that can be extended up high or in the ceiling which will help with the signal strength.  I hope there is an answer to this question.  Nonetheless, many thanks - MARSHELANGELO

Anyone know why there is an SMA Male and an RP SMA (the one with the female center) male? I Googled...

I was going to guess the same reason before I clicked the link and it confirmed it. 

It may help to prevent people who are less knowledgeable from simply hooking something up not intended by the designers or FCC regulations.  Obviously not impossible, but it requires more know how and/or effort to make a connection.  Some people will just look at it and say "darn, this won't fit" and give up on the idea.  If that happens, the intent of making it different worked.

If we are asking random goofy RF history, why do they call it a "UHF" connector?   (Nothing to do with trains, but it's a ham radio thing.  I always called them PL-259/SO-239 to be clear)

Note that the TMCC Buffer and the extended antenna have no connection either logically or electrically, each addresses a totally different and unique issue.

The TMCC Buffer is ONLY addressing track signal deficiencies, that being the 455khz signal out of the command base to the track.  The TMCC Buffer doesn't have any effect on the remote to base signals.

The extended antenna is ONLY addressing the remote to command base over the air transmission and reception.  The extended antenna has nothing to do with the track signal nor will it affect it one way or the other.

At my club, we have the legacy base, TMCC base, 2 TPC’s with 4- 180 watt powerhouses in a cabinet under the layout which is about the center of a 18’ x 38’ layout. 
We have no signal issues at all with the Legacy remote. At times, the cab- 1 does not respond if the antenna is up on a certain way but for 99% of the time, it works fine.

Ted, you may want to refer to my previous post.  You're talking about a sample of one!  There are tons of variables that can affect both the 2.4ghz link as well as the 455khz track signal.  This is not one-size-fits-all.

Every layout and every environment is different Bruce, what works for you may not work for someone else in a different environment.

 

Gentlemen, a thousand thanks for checking in on time,  Dave, thanks for the corrective oversight and Bruce, my layout is 12x30 and I wasn't sure, so I wanted a backup source for insurance, Gunrunnerjohn, I was able to cancel the order and order the correct device.  Again, I thank you all for your expertise and support. - MARSHELANGELO

Hey Greg, how has it been working for you? I'm interested in getting it too but reading through some of the reviews people say it's a bad product or the cord isn't good. I'm also trying to relocate the antenna due to my base being under the table. Thanks!

I have a drawer full of UHF connectors if you want some.

Just fyi, although I don’t like the UHF connector (SO239 and PL 259), I remember a test of the connector’s viability some years ago and it tested very well. Hardly caused an impedance bump at all and minimal loss I think from UHF and below. I though convert everything in my ham shack to BNC. It’s just easier and handles FCC rules power easily.
