This is installed stationary at my work, lately I had been getting drop outs and now the last 2 days nothing at all. Screen just says "Acquiring Signal" yet on the "antenna strength" screen I have all the blocks lit up. What I have tried- I tried adjusting the antenna, installed another antenna, powered down & reboot. I park my vehicle that has a different P-n-P in it next to where the antenna is and get good reception. Has my JVC took a dump?
