    Hi, I am taking my mast down to replace the standing rigging and would like some advice on an AI/VHS antenna and the cable I should choose. I am installing a Raymarine AIS650 with a Raymarine AIS100 AIS/VHF splitter so I can use the same antenna. You probably have answered this already in you posts, but I have just discovered them and thought I might just ask you directly since my mast in on the way down today! Thank so much. Caxton

    Hello John,,
    Thank you for all the info you have posted. I hope you can direct me to a specific area to read or to post this question and hope it is OK to contact you in this manner for direction and advice.

    I am working on installing M-802 on a Nauticat 33 Ketch. The best "backstay" for an antenna is one of the two split mainmast stays that terminate on the top of the cabin before the aft deck. The easiest location for the AT is in the aft locker, directly below and perhaps four feet below cabin top. This locker is located between the aft cabin sleeping area and the seating in the pilot house. Thus the antenna lead would run close to a sleeping area and a lounging area on its way to the backstay. My concern is regarding RF exposure. Would it make more sense to put the AT directly under the cabin top where backstay starts and reduce the antenna lead length? This greatly increases the ground strap installation. Thanks, David

    Hi John !! I am Guillermo, a beginner in ham, CP6GA,living in Bolivia.
    I bougth a radio Icom 802 and IT 140 tuner to install in my house.
    I would like to know how to connect a dipole antenna to the tuner, because it has a terminal for the antenna at the top, but that's not a coaxial connection.
    The other connection is grounded.
    It should connect the dipole one on land and the other to the output of the antenna?
    Many appreciate your comments

    I saw your recent post on SSB. We recently bought a sailboat with an SSB, which I have no experience with. Thanks for posting all the links, I'll be looking into them.

    Hi John, It's altairishgirl again. On the SSB, a few questions... We have the KaitoKA1103. We had a little wind up antenae on the boat that we ran up the mast. We knew of the 3968 sonrisa net and we picked up once, just barely enough to make out what it was. We just couldn't get much to come in, even here in Utah. Would you recommend anything else? a. Rid boat of interference. I read that to be anything electrical at all, boat breaker panels, phones, ipads TURN OFF entirely. Killing power at the boat breaker, is that enough? b. Create better antenae. I read that to run a short piece of coax (RG-58 with a properly installed PL-259 connector on the radio end) from the ssb to the backstay, and attach just the center conductor (?) to the backstay. c. know that there is a fine tuning dial on the kaito to play with. Once I have the new antenae in place, is there anything else I should try before trying it out? Thank you for the help again.

    Apparently, my reply, which included your email and links was cancelled because as a new member, I can't send email with links until I am a "trusted member"

    Hi John,

    I need to order a new connector cable that goes between the control head and the transceiver on my M802. I also need to order a new mic because of the coiled cable falling apart. Can you recommend a vendor for these parts.
    Thanks, Roger S/V Hanoah
