If anyone is interested I now have these in stock and available at $59. I tested it out and it did add about 25 to 30 feet as RTI advertised, but then again I am getting about 70 feet with the normal setup. In the short time I have been playing with this, I have experienced better all around performance over the standard IRF-6 antenna. I hope RTI makes this standard on future production. I have not tried this in dual antenna mode yet.
