[Amel Yacht Owners] Maintenance SSB antenna

My triatic stay is separated electrically by two ceramic insulators. Sorry I just left the boat. However the attached link is very similar in style to the ones I have. The insulators insulate the masts from the triatic stay and the coax is connected to the insulated section. This was installed by Amel. http://www.ebay.com/itm/like/371555128060?ul_noapp=true&chn=ps&lpid=82 Fair Winds Eric Kimberlite Amel Super Maramu #376

Good morning eveyone. I changed the triatic (main-mizzen) and now I have to reconnect a new coax (RG213) to the steel cable. Someone could give me direction on how to do and how to isolate it from the elements? Thank you all and good wind. Enio Rossi |

This goes well, thank you Eric. I,ve just done that. My problem is how to connect the coax cable that comes from the mizzen to the insulated part of the triatic. . Because if the triatic antenna wants be a dipole should also be insulated in the middle and have two half antennas. Or not? Greetings and good winds. Enio

The triatic antenna is not a dipole. It is connected to the antenna part of the triatic close to the insulator nearest the mizzen mast. The non-insulated part is about a foot long on either end. Fair Winds Eric Kimberlite Amel Super Maramu #376

Thanks Eric, the insulated part of triatic is not a dipole. Well, the copper core of the coaxial is connected to the insulated part of the triatic, but WHERE do I connect the shielding braid? A building site has replaced the triatic without reconnecting cables........

The insulated triatic is not useable as an SSB antenna.To answer the question though, the core of the coax is connected to the insulated triatic, the shiled is not connected to anything.
The triatic may work as a weatherfax receiver (its original intention) but as an SSB antenna it is useless...I know from experience. I connected my antenna wire from the tuner to the main backstay and it worked well. WE now have an insulated backstay for our SSB antenna...insulated only to prevent shocking the crew...the Amel rig is not grounded. Cheers Alan Elyse SM437 |

Alan, I have a Maramu and use the backstay as my SSB antenna. It's been working well. I was wondering if lengthening the antenna by connecting my insulated triatic with gto-15 cable would improve reception/transmission. Thanks for any advise you can offer.

Hi Bob,
If you have an automatic tuner there would be no advantage in connecting the triatic to your backstay. The tuner tunes the frequency to the length of the antenna automatically. If you don't have an auto tuner then you need to be aware of the length of your antenna relative to the frequencies you want to use. Some will work well, others hardly at all. Where in Fiji are you ? You survived WINSTON ok ? Cheers Alan Elyse SM437 |

Thanks Alan for the quick reply. I do have an automatic tuner and wondered if tuning to the longer physical length by adding in the triatic would be an advantage. In at in a pit at Vuda Marina and we were spared the worst of the cyclone. I came back to check the condition myself and found Chara in the same condition as I left her. Much relieved! There are three other Amels here and all look good. Thanks again, Bob On Mar 2, 2016, at 12:24 PM, divanz620@... [amelyachtowners] <amelyachtowners@...> wrote:

Hi Bob,
Good to know they are all OK...I saw a photo of Reve de Lune and Amelit in the cyclone pits and they are both apparently OK. I doubt its worth the trouble with the triatic stay, good ground is more important. Cheers Alan Elyse SM437 |

HI, You just use the core of the coax n use the triatic for navtex or weather fax. Fair Winds Eric

If you have a newer SSB (e.g., Icom 802) with a dedicated DSC receiver, the triatic would be good for that as well. Bill Kinney S/V Harmonie SM #160 Hollywood Florida On Mar 2, 2016, at 00:09, sailormon kimberlite@... [amelyachtowners] <amelyachtowners@...> wrote:
