ICOM M330G- Ground; GPS Antenna
Posted: Sun May 08, 2022 8:19 am
I'm installing a new fixed-mount [ICOM M330G] VHF Marine Band radio on my 1986 Outrage 18.
GROUND CONNECTION.
The [ICOM M330G] as a red and black [power]. I will connect the black conductor to the battery negative post. In addition, there is a ground screw post connector. The [installation] instructions say to bond the ground post on the radio to "vessel ground". The only grounding on my Outrage is via the battery.
Q1: Do I need to add an additional ground wire from the VHF screw ground connection to the negative battery post?
Q2: Is "vessel ground" more applicable to a larger vessel where you may have a large grounding system separate from the vessel connected to anodes?
GNSS ANTENNA:
The [ICOM M330G] radio its own GNSS receiver. There is a connector on rear panel of the ICM M330G radio for a GNSS antenna. The GNSS antenna is a square puck that comes with 3M double-sided tape to fasten it to the boat. The instructions give no rules for where the puck should be installed or not installed.
Q3: should the GNSS antenna be installed inside the console?
Q4: would a line-of-sight skyward placement be best?
Thanks for any help.

ASIDE: I rarely go out of sight of land in Mahone Bay. I have never lost no cellular telephone service [while in Mahone Bay]. [Mahone Bay] has almost no commercial traffic and not a huge amount of pleasure vessels. Mahone Bay is a huge bay full of islands. With the lack of people and boats, Mahone Bay is a wonderful and relaxing area to boat.
Our spring weather has been cool but we are getting some high air temperatures of 70-degrees-F later this week. We had frost this morning.
