I am putting a bimini top on my 72 Nauset (Mills, Of course) and currently have an 8' VHF antenna mounted to the side of the console with a ratchet mount. Once the top is on I will not be able to use this configuration anymore. I saw Larry's setup but can't make that work on the Nauset without exposed wires, I considered moving it to the back but then I will have to run the transducer and antenna wires together in the tunnel which is not recommended. Can I go to a 3' antenna and get decent reception? I mostly boat inland waters so distance may not be a problem. Any thoughts? Bruce

I have a 3' metal whip antenna that is attached to a rail on my console. It seems to work fine (I boat mostly on the Potomac River with occasional jaunts to the Ches. Bay.) The range is kind of limited with the shorter antenna, but even if the antenna was 8' long I would not be able to transmit around the river bend...I would say go for it...

I used a 3' Shakespeare metal whip antenna on my 15' SS with no problems. This is a 3 db antenna versus 6 db for most 8' antennas, which may limit the range somewhat as Dave suggests. The 3 db antenna could actually perform better than a 6 db under adverse conditions (heavy seas, rolling, etc.)with its wider beam.

Thanks for the info. I think it is my best solution. Bruce

My transducer cable and VHF cable are both
in the tunnel of my Montauk. No problems.

And VHF is a little less line of sight than
the party line. I regularly talk from
Monterey Harbor to Carmel Bay, with
about three miles of granite a few hundred
feet high in between.

Bruce -

Both the transducer and the antenna cables are coax and will be fine down the same tunnel togeather. If perchance the transducer isn't (the antenna most definately is coax) the only thing that may happen is that the depthsounder might get some false signals, but only when you are transmitting.

I've run both in five Whaler tunnels so far, and never noticed a problem.

We routinely run antenna coax from fairly high powered transmitters (100 watt VHF and UHF units) bundled togeather with no problems.

The two montauks I had, we mounted the 8' antenna on the stern, inside gunnel wall. Positioned it so the bracket allowed the antenna to rest on the top of (this may get confusing, read slow) horizontal portion of the grabrail holdoff brackets. Got that? And we positioned it fore/aft so that the tip of the antenna went (by bending it) under the first holdoff bracket of the bow rail.

Best - Don

brainfart... add the following to the last post:

So when trailering, the antenna stowed and didn't rattle or need additional support.
Did notice some engine noise in one installation, but none of the others.

To all of you,
So I guess I am better off with the 8' antenna? Is that the final decision of the crowd? I am wondering if the antenna in the stern is a problem for fishing? Back to the question of range loss. Would I decrease the range enough that I would regret it? Shakespeare makes a quick disconnect 3' model that I thought might be nice? I sure do appreciate all your thoughts! Brainfarts and all!

Bruce, for what it's worth and without commenting on it's desireability, here is the quote from the 1971 Owners Manual that came with my new 1971 16 footer: (page 12)

(picture shows a Mahogany center console, with the 8' antenna installed vertically on the port side, passing along side the port forward corner of the windshield - base of the antenna is near the bottom of the top portion of the 2 piece console)

"the radio antenna installation is positioned to fit between the windshield zipper joint of the FLYING TOP set. (that would mean where the eisenglass windshield section zips onto the front edge of the Flying top - LHG note) Antennas of two part construction are desireable because they can be disassembled for trailering, fishing, etc. (is 1970 before ratch lay-downs were invented? - LHG note)
Broken down, they are conveniently stored outside the side rails, not interfering with the activity at hand." (did Don M suggest this also?)

I think this may mean that if you bought the Flying Top instead of the Sun Top, the antenna in this position would clear the top.

I always appreciate your quotes from the many manuals you must own. My vote was the fly top. However I was out voted by my better half. She prefers the coverage of the sun top. I think I will play with Don's ideas and see what I can come up with. Thanks, Bruce

stay with the 8 foot. You can't beat the range. Remember, communications is your "lifeline". You should base this on your "range" of your fishing or cruising expeditions. I have a 19 ft outrgage CC, and faced the same dilemma with the Bimini/antennae. I can send you a picture of where I mounted mine, just let me know. I go offshore between 10 and 30 miles, so it is a "must"(8ft)for my safety/comfort factor.

Thanks for the advice. I have decided to stay with the 8' for now. We are going to wait on the suntop so we can leave the antenna where it is for now. We are thinking of giving the Nauset to the boys and buying a bigger Whaler for us.
