Author Topic:   Antenna Installation Without Cutting Holes

I'm trying to install an (eight-foot) fiberglass antenna on my [2007 Boston Whaler 190 MONTAUK]. I think I would like it on the forward starboard gunwale. [Explain the technique for] pulling the cable through under the deck or under the gunwale without cutting 10 new holes. Thanks Dave

Dave--While I can't offer assistance on routing the wiring, consider the location carefully.

My Outrage had an 8-foot antenna on a ratchet mount on the gunwale directly across from the console. http://picasaweb.google.com/CascoBayOutrage/1991Outrage17I/ photo#5012257117250288306
Every person wanted to grab it getting into the boat.

I moved it to the stern rail.

Dave,

Have you considerd mounting it on part of the console railing? With a SS rail mount bracket it could be mounted higher for better performance and would interfere with fore and aft passenger movement to only a small degree. It could also be folded forward or aft as needed to be completely out of the way of any cover. The cable run would be short and no cable holes would be required.

Of course, if you use a bimini top most of the time you should ignore all the above.

Agree with CBO that an aft rail would be a good spot, too.

The length of the radiating element of the antenna does not affect how its transmission line is routed from the antenna to the transmitter.

In a Boston Whaler there is generally no free space in the bilge, and any rigging has to be run via a rigging tunnel incorporated into the hull. I do not advise trying to route any cables through the hull except via existing tunnels.

To run an antenna transmission line through the existing tunnel, just follow the path that the existing wiring is using. Use an electrician's fish tape to feed a pull wire into the tunnel. Then use the pull wire to pull in the transmission line for the radio antenna.

If you need advice specific to the Boston Whaler 190 MONTAUK, I suggest you contact Boston Whaler and ask their advice about routing a radio transmission line. Boston Whaler offers the option of a pre-installed VHF Marine Band radio, and I would be guided by their recommendations.They have probably given this problem some thought, and their solution is likely to be a good one.

I would not recommend trying to bore a hole in the hull simply to provide a path for the transmission line for your VHF Marine Band radio. That sort of modification seems like a drastic solution to a minor problem. The hull warranty may be affected if you start boring holes into it.

It may very well be that the only path for the transmission line from an antenna located on the stern quarter gunwale to the center console will be via the existing rigging tunnel. If the transmission line of the antenna is not long enough to reach, I suggest that you do not try to make any splice or joint in the radio transmission line which will wind up being located in the rigging tunnel. It will be difficult to make such a splice or joint that can be completely protected against submersion in water, and in the rigging tunnel it is a fact of life that some water may be present from time to time.

Mounting the antenna on the console will also have everybody
trying to use it as a handle. I had a friend with the
antenna there. I put my hand on it a number of times.

The cable length varies from antenna model to antenna model.
The inexpensive Shakespere's have a 15' cable, the more
expensive (and better) Shakespere Galaxy's generally have a
20' cable, and better quality cable. On my '97ish Montauk,
15' isn't a enough, 20' is. Dunno about 190 Montauk.

The rigging tunnel is probably the only way to get there.
You may not need a fish. More recent whalers leave a string
in the rigging tunnel for just this reason. Use the string
to pull the cable and new piece of string (for the next
project).

Dave -

After some research, it appears you have two good options.

Option A)
Mount the antenna on the rail, using a ratcheting rail mount. like this http://store.hamiltonmarine.com/browse.cfm/4,21901.htm If so, you will have no holes for the antenna and 1 hole for the wire to enter the console. To cover the hole for the cable you can use either a clam shell vent (3 holes)
http://store.hamiltonmarine.com/browse.cfm/4,8180.htm
or a grommet (3 holes)
http://www.outdoorsuperstore.com/product.asp?prod=421272

Option B)

Mount it on the stern rail using the same mount as above, route the cable under stern seat and route it up the rigging tunnel. No holes.

There should be an extra piece of rope in the tunnel left specifically for pulling wires up the tunnel. If there isn't you can use a fish tape to get string up/down the tunnel. Some say to start the fish tape at the console end and work back.

Hope this helps.

Thanks for the sugestions I'm kind of hard headed on this one. I owned a 17' montok for 20 yaers before buying my 190 and went through several radios and different antenna locations. I think at one time or another I had an antenna at all the spots named. I'm lucky in that I live a short drive away from the Whaler plant and am going to go by to see how they fit the liner to the hull. I have already made several improvements to my 190 and there is actually some working room between the deck and hull.To anyone who is in the market for a 19' center consel I challange them to find a boat with as much room and deck space as this boat. I never thought I would ever part from my 17 montok but what an upgrade. Thanks for the replies and Thanks to Whaler for such a great boat. See ya on the wave dave

If you discover some new revelations about how the Unibond hull of the Boston Whaler 190 MONTAUK is constructed, please post your article to the POST-CLASSIC discussion.

You may also want to consider that the further forward you mount the antenna, the more stress it will subjected to while underway in a chop.
