Brian, I used a Follow me for several years and was able to get satellite TV at anchor most of the time and only in very smooth seas and slow speed under way, but it was good as far Belize before I lost signal. I had to replace the drive unit one time. My cruising buddy found it imperative to keep up with Wall Street and wile on a trip home he invested in a larger dish and was able to receive a signal further south. Marv. heide163@aol.com
