Cut antenna wire raymarine 300waas gps

The issue is related to the antenna, either bad connection, low voltage or faulty gps. Start by checking the voltage supplied to the antenna (most probably through SeaTalk from the plotter), if you find this to be 11V or bellow - beef it up by adding external 12V. You can also check the wiring, if all looks ok - it is time to get a new gps antenna. Raymarine has a retrofit pack for the new RS130 which also includes SeaTalk ng converter. With some luck it's only the power...

There are 5 wires running out of the antenna and the 5 wires that you need to connect.

I had to replace a GPS antenna unit with cable. Sometimes, during bad weather or strong sun, I lost FIX on satellites. Cleaning the top of antenna did not help. Unit from Ebay was also a junk. Get a new one after testing display on a friend boat.

GPS antenna has to have a clear view of the sky.

Guys, most likely the litium battery is eol. Buy a new litium 3 volts battery for 3-4 euro's with soldering points . Use a pair of scissors, note the plus and minus side of the poles and carefully cut out the battery leaving enough metal to solder a replacement battery. Solder the replacement battery, and the problem is fixed. You're ready for another 6 years of fun saving 300 USD for a new GPS!

1. All your E Series MUST HAVE the same Software 5.23
2 You must set the Divice where the GPS Signal comes in as MASTER
all the other Repeater
3. Your GPS antena shoud be mounted outside

The antenna should be replace by raystar 125.

The GPS antenna with the 300 is not a GPS receiver unit like all the later Raymarine units and is no longer made. However the unit will accept input from a GPS receiver with Seatalk output. So you could use a 112, 120 or 125 receiver.

Hi. I have G series Raymarine and I listen the noise when swtich on I am not shure , may be from the ventilation (the fan).
I not find troubleshooting to G raymarine, I hope find the soulatoin thanks.

If it is an RS 120 or an RS112 antenna you do not need to change it.These are both active antennas in other words they do all the gps computing in the unit itself. You need to look at the wire from the antenna. If it is a coax cable(2 wire) it will not work.If it is 3 or 4 wires it will work. If 3 wire (red ,silver yellow) just hook up color for color.If 4 wire you are going to have to figure out the wiring for it from the units wiring diagram.That could be a big enough pain that you might be inclined to change to the new antenna. If you wire the new RS125 antenna you must wire it to the seatalk buss. The seatalk wires are Red Silver and Yellow.The wire from the RS125 are red yellow silver green and brown.Wire as follow to your sea talk cable.Yellow to Yellow, red to red , silver to silver, green to red, brown to silver.
Hope this helps.
