Author Topic: 2 Meter Rig On A Sailboat  (Read 1259 times)

I have a 26' sailboat that I am thinking of placing a 2 meter IC-2200 rig in.  My plans were to use a J-Pole antenna made from 300 ohm TV antenna wire, coax, etc.  This antenna would be brought up into the rigging via a rope and will Be far enough away from other metal up there. 

I chose the J-Pole route because of the hassle of running coax up the mast to a permanent (slightly cut down VHF Marine antenna) antenna, the possibility of snags on sails, etc.

My questions are:
1.) Will a J-Pole handle the 65 watt maximum output the rig can generate?
2.) Does this sound practical?
3.) How corrosion resistant are Anderson power connectors?  I will remove the rig when not in use.

Thanks

PS: Please notice I did not mention using the Rig as a marine radio.  I have a VHF marine radio on board dedicated just to that.

It should work. 65W should be okay unless the SWR goes high due to the antenna getting wet.

For a permanent installation you might want to consider one of the sealed marine 2M band antennas. You can find them with Google. Designed like a 1/2 wave marine antenna but for the 2M ham band.

I use a Shakespear A-B type VHFantenna switch to switch my 2M mobile rig into the marine radio antenna line.  With my old Shakespear marine antenna, I had to rig up a small matching network to bring the SWR in line on 2M.  My newer Shakespear marine antenna is broad banded and handles the 2M rig just fine.

Make a SO239 connector ground plane out of stainless steel wire. Wink

The J-pole will work fine. W0FM has a good suggestion to switch into the marine VHF antenna. The coax cable loss is high enough that the VSWR should be less than 3:1 even if the antenna has a very high VSWR. If this is too high for your transceiver a 50 watt, 3 dB attenuator can be added in line or use an MFJ-921 VHF antenna tuner ($89.95).
