Hi  Bob,

  

 I am  installing a VHF based APRS tracker on the RV7.  The kit came with a wimpy  antenna not suitable for installing on the outside of the aircraft.  Since  the APRS out uses 144.XX MHz frequency, I plan on using an old aircraft  grade LORAN antenna which is tuned for the same frequency.

  

 My  question is how to elegantly connect the fine line supplied with the tracker to  the BNC of the antenna. The existing feed line is some small diameter I had not  anticipated.  It's about 1/8" in diameter.  Are there BNC made for  this (probably are somewhere but I don't really want to wait for an order to  come in) or can I make a solder connection between the 1/8" feed line and a  short piece of RG400 I have here?  Then BNC that as usual.  If so,  what you recommend this joint look like?

  

 Thanks

  

 Bevan

Is it the AP510?  I'm using one of those with a cheap converter like this:

It doesn't completely meet your needs as far as having to wait for an order, but with their Prime shipping if you order it now, you'll have a backup on the way in case you don't like the home brewed solutions as of two days from now.

Can you provide a picture or a model number of the tracker you’re using?

Could you do an SMA to BNC adapter at the tracker and just hook up there? 	  Quote:
