Open the box and let us know what is inside. I also looked at the picture, there is no tuning knob on the outside as far as I can see. The box should be held together with screws, most of these small boxes are. More than likely there is an inductor of some sort inside. See if it is adjustable or not. There has to be some sort of adjustment…. if not the antenna is not going to be very good. You should also use a field strength meter to set the antenna up,if you had one, you could just tune for max strength. I have found that a CB field strenght meter will work for this purpose. That is what I use. Some CB meters may not work but I have found most will. At best, I wont expect anymore range with this antenna than with your talking house ten foot wire. The Talking House Transmitter has a nice built in matching network which works real good with the ten foot antenna. Im not sure how long that green wire is, if its longer than 10 feet then it will radiate more if tuned, but there has to be a way to tune it. Take the box apart and let us know what is inside. I have the Talking house external antenna and it works real good, however I have also worked with the same 102 inch whip and using simple loading coils from hand wound to variable ferrite slug tuned coils and the results are pretty much the same as with the Talking House external tuner. I thought maybe the TH tuner would be higher Q or somthing but any loading coil made right will work just as good from my experience and practice. The TH tuner box is nice though because you can just open the case and dial for max output.
