I am about to order the parts needed to do the ARGtek antenna mod but had a few questions I can't seem to google an answer for. I see they have both a 10dbi and a 7dbi version. Also, the 10dbi pictures, one middle antenna looks longer than another (in the photos on eBay). Which one is better? I trust I am making a decent decision here. I know there is the other mod (the ITELITE), but is it really that much better? Seems I will be satisfied with 3x-4x my current range which is what the ARGtek seems to yield. Thanks for the help.
