650 shark fins and boats

The silicone fusing tape is easy to find. It is easy to work and very stable as far as solvents and temperature. It is also a little weak or on a positive note, easy to tear off.

 

There is also an EPR version (Ethylene Propylene Rubber):

The EPR version is stronger and harder to tear. Either will work though I prefer the EPR for around the house repairs and taping wires. It takes a little longer to fuse. The silicon version fuses quickly. The tape should be very clean with no water, dust, etc., on it, so it can fuse. Make sure you stretch it a lot (2 to 1) while wrapping. The tension and stretch causes it to fuse quickly.

 

One downside to both tapes. If you are taping multiple splices, when they touch, they will fuse with each other.

hobo: " Has anyone put Alp 650's on a boat? "

yes, actually...

" Gonna be at sea for 5 months. "

that calls for some special preparation, and some periodic maintenance...

 

" it's a daunting prospect "

unreasonable expectations..?

vin asked: " Why not Yagi antennas? "

but I'd suggest omni's...(Shure, others)  maybe check with antenna specialists, and look for marine antennae (sic) that can be had for the wireless mic bands...

BNC's should be fine. BNC stands for Bayonet Naval Connector.

 

Hum, after Wilipedia and other sources,

 

Origin:

The connector was named the BNC (for Bayonet Neill–Concelman) after its bayonet mount locking mechanism and its inventors, Paul Neill and Carl Concelman.

just a cent or two,

I set up an almost identical situation a few years ago for a show called Big Shrimpin on History. I used an ALP620 on the back deck of the 100 foot boat and a SNA600 in the wheelhouse. They were both going to a Lectro Venue system. Two camera guys on the boats, no audio guy and we waived goodbye and saw them again a few months later.

The ALP620's were mounted on a pole on the back deck and I did pretty much exactly what Larry suggested: bag them with thick poly and do a few zip ties on the cable to seal it up. I through in a few bags of that moisture remover (Larry said the name earlier in the thread and it escapes me now). The antennas came back in perfect condition with no damage to the connectors. The mafer's that were holding them to the pole and which were not covered were rusted together and had to be cut off.

If you want to shoot me an email I'll be more than happy to walk you through some of the other aspects of that show that we found useful.

strangely enough, the german Wikipedia (btw, really like your typo ;) ) also lists Bayonet Nail Connector, Bayonet Navy Connector, British Naval Connector, Bayonet Nut Connector, Bayonet Naur Connector or Bayonet Norm Connector in addition to Neil Concelman Connector.

Thanks for those ethymological inputs.

I always thought that it was the initials of inventor. Now it is easier to remember.

 

 

Are you the Masaki who used to work on my Fostex PD4 at SVC in London all those years ago?

No unfortunately not. I'm always based in Geneva, Switzerland from '99

Masaki is not common first name, maybe Masa-aki ?

 

Sorry to hijacked the thread

Got the same impression (they provide TC and that's it) BUT the integration of the CL-Wifi plugin for the Beetle unit +Tonmeister app makes me think also they might have concluded an agreement somewhere...

 

KT Systems, Chandler's Ford, UK. I am not suggesting that these will give marine protection but they protect the electronics from the weather without adding windage to the shark fin itself.

Interesting tim. I'd be worried it would absorbs moisture over time if it wasn't dried out but have you got a product name/number and I'll get on to them

Have you used them?

They are Cordura so will not absorb moisture. They were only delivered last week so they are dust covers at the moment. In the past we have taped poly bags around the electronics to keep the rain out as bags over the whole shark fin can increase the windage and cause chaos. These should keep most of the rain out of the business end and give some protection. No part number as yet but KT will know what you are talking about if you ask for rain covers for active shark fins.

Month in and this far all four arrays are holding up.

For budgetary reasons couldn't squeeze out 4 of the kt covers but think they would be a good option if ppl were looking.

Have positioned the arrays high on the mast so as to keep out of the salt spray for the most part. Bags have lasted about a fortnight or two at a time before holes start to happen usually on the points of the fins.

Positioning and angle of the fins has also been important. Having them high up and pointing down and away mean if any moisture gets in the bags it runs off and never thru the electronics.

Having the crews rebag them now every time they come to port.

Also be careful where ppl plonk generators. One of the boats added a generator and this happened.
