Bruce is correct that Beverage antenna installation and maintenance brings on
the risk of life changing Lyme disease. Lyme disease is present in many areas
of the world, but particularly in the non-arid areas of the United States,
Canada and Europe.

Permethrin treated clothing (socks, pants and long sleeve shirt) is
exceptionally effective at repelling ticks.

Clothing can be purchased pretreated with Permethrin. Commercially treated
clothing remains effective after dozens of washings. Look for the trademarks
"Insect Shield" and "Bug Shield" in sporting goods stores or online:
