Why do you need a preamp in the mobile? Most new rigs are great at sensitivity. You must also remember that if you are mobile, Intermod is just around the corner at these high sensitivity preamps. Preamps, as a rule, should be as close to the antenna as mechanically possible. Good Luck, 73, Dee, NB2F

My question is, what is close to the antenna - 1ft., 5ft., 10ft.? Ideally, I would probably mount it about 5-6ft. from the antenna (1/4 wave) - would this be acceptable? Any additional advice would be appreciated! Zack KD8KSN _______________________________________________ Sent via [email protected]. Opinions expressed are those of the author. Not an AMSAT-NA member?
