Hi folks,

 

Have just pulled apart a friends tv aerial, they were having dodgy reception on most chanels.

 

The pc board is corroded with a brake in one of the tracks.

 

Is there any reason I can't just solder a wire as a "jumper" as a temp fix ?

 

Guess the best way to find out is try, can't make things worse.

 

Just wondering if there was any traps with doing this.

 

Thanks

You should hopefully be able to get it going again.

 

If it's an older board without an F connector, make sure you lightly sand the screw clamp connection area, and strip back the cable coming in to fresh wire before reattaching.

All the usuals apply.  Don't burn yourself, don't solder batteries, don't like the end of the tip, don't run your lead through water etc

 

I figure if you're asking if you can solder it, then you're capable wink

 

 

 

I often use a straight section cut out of a paper clip to repair joins.  Just lay it on the track and solder either side.  Often easier/more effective (gives the board back some strength) than taking a jumper wire loop between the two points.

Should be able to.

 

Back when I was involved with antenna installers it seemed common to leave things not quite waterproof inorder to get a call back in a few years time to replace things. So once done, I would paint the board up with something and make sure that the box is mounted with the holes facing down etc.

Thanks folks

 

Just setting up for a play

 

Yep not liking the tip of the iron is a real good tip, the flux residue tastes horrible  :)

 

Unfortunately the tracks are too fine and close together

 

I cant really understand why they made it that way, except to make more surface area to corrode and built in obsolescence etc

 

Or am I being a tad cynical .......

because the board will be a transformer to match the ballanced antenna elements to the unbalanced coax cable. Conventional transfromer based baluns have much loss at UHF so are best avoided.

Thanks folks

 

Working perfectly

 

A bit of Kiwi #8 thought applied to it seems to have worked

 

The board is corroded, it's only a temp patch
