I purchased this no ground plain model because I was not getting good results with a Midland GMRS antenna. I have an aluminum body F150 with the antenna mount on a large grill guard. Not enough steel for a proper ground plain. The Laird vastly improved reception and transmission on a Kenwood NX-1800HAUK2 programmed for GMRS. I would definitely recommend this for anyone that does not have a proper ground plain.
