I have looked on the web for a mod to get 30 meters on a Huster 4 BTV and no dice. Does anyone know of a clever way to add 30 meters to the antenna aside from buying the kit from DX Engineering?

First result in a Google search on "4BTV Antenna" is the web site of the manufacturer (New-Tronics) where you'll find that there's a 30-Meter Trap Kit for the 4BTV.

Part Number: 30-MKT
Price: $47.93 (Plus shipping, I presume)

I made a 30M addition to my Butternut HF-2V as follows.  I U-bolted a very light weight plastic cross arm in the middle of the antenna and ran a 23.5 ft piece of 18g wire from the feed point through a loop connected to the cross arm the cross arm, to a piece of nylon twine and tied it to the top of the vertical.  I adjusted the length to get resonance on 30M.  Worked fine and cost me nothing.

You could just build a separate antenna for 30 meters.
A 47 ft dipole has 23.5 ft to a side, it's not that big!  Or, since you already have a vertical ground plane for the 4BTV you could just add a 23.5 ft vertical and separate feed.

Try W9OY's procedure.  On Ham Universe under Antenna Design there was a procedure to add 17 and 12 Meters to the 4, 5 , and 6 BTV Hustler Antennas.  I installed this on my Hustler 6 BTV.  The 6 BTV already has 30 Meters on it but did not have 17 or 12 meters.  It was very easy to install on my 6 BTV and it works GREAT !!   I did not even have to retune the antenna on the other bands at this location.  73's  N0CGF Dennis
