Hi all, I just ordered an Icom 2730a transceiver for my car. I'm leaning towards going with the Larsen NMO 2/70b antenna. I have a Jeep grand cherokee and thinking about mounting it on a bracket at the rear hatch so that the top of the antenna will be probably 1' above the roof of the car. My question was that at 50w on VHF/UHF is the RF radiation too high given that my kids will be sitting within 5' of the antenna? Is there a better place to put the antenna to reduce radiation? When I input figures in the RF radiation calculator it says I need to be about 10' away, which isn't really possible in a car. My second question has to do with grounding the antenna. If it's mounted to plastic brake light housing would it be a good idea to run a separate ground cable from the metal nmo bracket to the negative battery terminal? Thanks for the help in advance!
