Chet Sturgis of Chicago, Illinois, asks:
“Recently, I installed a cell phone amplifierI dont recall the manufacturers nameto increase my range when Im sailing off the coast. Although range has improved, when Im back in my slip I cant get good reception from someone who is calling me from just several hundred yards away until I turn off the amplifier. What am I doing wrong?”
Gordon West replies:
Many inexpensive imported and uncertified cellular amplifierswhich is what I think you havetend to oscillate when they are surrounded by multiple cell-phone users. Thats why you are having reception problems when youre in your marina. All the established manufacturers have worked hard to minimize this problem, which is why I expect the FCC will take action soon on the makers of these pieces of equipment.
