Transponder Ant.

[MIKE <mike.a0011109@infotrade.co.uk>]

Could anyone help please with any information about a good transponer ant and 
G.P.S
ant - I am not far off putting the lid on my Europa and want to get as much
wiring in as possible. I believe there is a good Txp  available from the U.S.A
but cannot find out who and how much.
Also has anyone fitted a skyflash strobe system and if so where is the best 
place
for the head and method of mounting.
Many thanks. Mike.96
