I've been searching the archives and find a lot of previous Q&A but can't seem to find the right answer. I've had my P3A for about a month after losing my P2V. Is it necessary to buy additional equipment to take advantage of Lightbridge? I'm drone broke right now and can't afford much more outlay. I hear of video feedback from as much as three miles out but my video on my LG 8.3 tablet gets really bad at about 1/2 mile. Thanks in advance for any feedback.
