I use these to solidly ground 146/440 mobile installations while they are at the cottage. These radios have no other ground connections and the antennas are not grounded to the attic. The antenna and ground remain connected to the radio when I unscrew the connector for portable use. Not really used for lightning protection but can help with surges. For this purpose they are inexpensive and do what I need.
