I converted my two Cab1 with this method, and while it work very well, the mod makes the remote top heavy and kind of cumbersome.  Even though it's a lot shorter than the original it's heavier.   Since the conversion I have had one Cab1 fail and since I'm Legacy I purchased a Cab1l to supplement my Legacy remotes.  Much lighter and accesses some of the engine Legacy features.   My last Cab1 has been regulated to bench use.

Thanks.  I'm interested in converting to a rubber antenna, but would prefer something shorter than 10".  Any ideas?  Was a Legacy user for many years, nice for sure, but sold off my 990 and 993, now using TMCC again.  Back to the future, or forward to the past?  You decide, but also now running postwar track instead of S-trax, one transformer instead of nine, and seven engines with thirty cars instead of dozens and dozens of both (I just bought a few FlyerChief/Bluetooth engines for good measure) and having a great time with trains - once again.

It's possible to have an antenna of almost any length, you need a loading coil to match the frequency response.  In truth, for the CAB1, you can probably just AdLib one.  I have a bench CAB1 that I got tired of dealing with the 10" heavy rubber antenna, so I took a stiff length of coax and just chopped the outer braid off it and had an instant short 5" antenna that is also very light.  It works 30-40 feet from the base, a lot farther than I need.  It's not impedance matched, just hacked.

You could go for something more elaborate.

Just find some coax with BNC connectors.  Chop it to the length desired and strip the outside insulation and braid, you have an antenna.  I just tinkered with mine, it's more like 20 feet from the base before it started missing stuff.  Make it longer and it works better.  For better performance, there are doubtless bottom loaded 27mhz antennas that are fairly short.
