Member Removed Posted August 20, 2009 Report Share Posted August 20, 2009 I recently took my warrior 165 and engine for a service. picked the boat up and on the way back to where we store it we went under a low railway bridge and i heard a snapping noise. when we pulled over and looked i realised that i had forgotten to put the long VHF aerial down therefore snapping off about a foot of it off. What i am trying to find out is if it will still work ok and send and recieve signals. thanks guys Quote Link to comment Share on other sites More sharing options...
oysterboats Posted August 20, 2009 Report Share Posted August 20, 2009 iguess it depends how long the ariel was to start with its the metal band inside the ariel thats the important bit if that is damaged then its goodnight vienna you really need to power it up and try it if you are near the sea or anyone with a boat and vhf it may be possible to contact via the radio either by listening in or transmitting to them or if you have a handheld as a spare try calling that and you should have a good idea if it works or not you would need to cap the break off i would have thought tho Quote Link to comment Share on other sites More sharing options...
gaffa Posted August 20, 2009 Report Share Posted August 20, 2009 Careful Sea Eagle If the aerial has become open-circuit, using the VHF in Transmit mode could damage it. They dont like transmitting into an "Open Load". I suggest you replace the Aerial. Its cheaper than a new VHF Peteg Quote Link to comment Share on other sites More sharing options...
Brian Posted August 21, 2009 Report Share Posted August 21, 2009 I agree with Gaffa. If the aerial is suspect, don't transmit you could fry the output stage of the VHF. An aerial is tuned to the operating frequency, if it's now shorter it's resonant frequency will have changed and it will not radiate the full power, some will be reflected and blow the output stage. The only way to test it is with a VHF VSWR meter (not a CB VSWR meter). Where are you located, I have a professional VSWR meter that covers the marine band frequencies.

Graham Nash Posted August 21, 2009 Report Share Posted August 21, 2009 Agreed. Almost certainly your aerial will receive reasonably well with a foot missing from it, but the reflected power during transmit could cause damage to the output of your transmitter. Best get it checked or replace i'm afraid. Quote Link to comment Share on other sites More sharing options...
Paul D Posted August 21, 2009 Report Share Posted August 21, 2009 Spot on. It is no use now it has had its length changed. You will need to replace it.# Quote Link to comment Share on other sites More sharing options...
