Antenna's are important too.
Shakespeare mount pt # 4187- HD
Antenna Mount shim kit pt # Shakespeare 414
Digital 529 - antenna...... I run the 529-VB = Black antenna.... I like it cause it's different and matches some of the boat trim.
If you want White........ Digital 529VW
I use Blue Seas Cable clam pt# 1002 to pass the coax thru the top in a waterproof fashion.
Most installers use a stainless clam shell...... I hate them. They squirt them full of silicone.
When and if the antenna has to be changed out.... It much faster with the Digital and Cable clam.
No cutting......No soldering........No crimping.
Digital uses a pripertory small end and a adapter screws on it , to connect to the VHF.
