Can anyone advice on the following problem
 
On my Legacy I have UPS stack with one SL30, one NAV antenna on the right
wingtip and an HSI  When I dial a VOR I get very a good reception signal.
When I dial an ILS it looks as if the signal is good. Then I turn to intercept the localiser. Between 30° and 20° before the ILS inbound track I lost the signal for
about 3 to 5 seconds (I get the red flag on the HSI).
This happens allways since day 1 either turning right or left and only for
ILS.
I check the antenna connections and it is OK.
 
1.What kind of tests should I perform in order to discover from where come
this problem ?
2.Do you know of any problems with the NAV antenna on Legacy ?
3. Has someone installed a second NAV antenna (external ?) and what model
?
 
Thank you to help
