I questioned the lousy reception I was getting with an antenna that looked like your BT-87. Well I ordered the BT-87 and with the expert advice I got it went in with no trouble at all. It works fantastic, the best antenna I've ever owned. the teck support is fantastic as well. A great company to deal with, and great products.The only complaint I have is some of the venders that carry your products don't seam to care much about weather your happy with them and if you need help good luck. You are free to use my name or review as you deem necessary, I am truley a satified customer, and will look for you to fill all my motorcycle needs.
