OK, so I'm new to the hobby and not licensed yet. Classes start next week and I'll take the test in about a month but I'm getting prepared for being able to TX soon.
So I bought a Yaesu FT-991 with an ATAS 120a thinking that I was set for everything. I found out in the general section here that I would need another antenna for 2 meter and 440. Which for me will be important for me. So I guess I'll add a Larsen NMO2/70B to the list.
So I guess if someone could help me with a few things I would be so grateful.
There are two coaxial antenna connections on the back of the FT-991. An HF connection and a UHF/VHF connection. Although I'm going to have an installer mount the antennas and hook up the radio, I don't even know which antenna goes to which connection.
I also plan on mounting the antennas to the top of the bed of my truck behind the window. The ATAS 120a on the driver side and the Larsen NMO2/70B on the passenger side. Will I get any interference or have problems with them being so close to each other?
I also will need something to switch between antennas like a duplexer? when I change frequencies and I would like help with that as well.
I have read K0BG.com about grounding and have grounded all four corners of my bed to the frame and both sides of the cab to the frame and when the radio is installed I'll have them run a ground cable from the ground on the radio to the grounding post in the engine compartment.
Is there anything I'm missing? I hate to ask so much but I don't have an Elmer yet and I thought the brain power here might be able to help without even breaking a sweat!
Thanks in advance
