I remember my avionics tech telling me that it was not recommended to double
up the antenna of a GNS 430 with anotherNAV--especially the older ones.
Could be a factor.

Hi!

I have a SL30 and a GNS 430 in my plane. They use the same antenna via a
splitter.
When I dial in the same VOR in both units the SL30 catches up the
radials always between 20 and 50 nautical miles earlier than the GNS
430! (Altitude about 3000 ft, flat area)

Is this normal?
What is your experience?
How far away do you have a reception of a VOR with your GNS 430?

*** I have a similar experience. My GNS-430 is clearly less sensitive
than
NAV2, a KX170B, even though they use the same antenna. I had assumed it
was
because the '430 has a wideband front end, whereas the KX170B, a much
older
technology, has a varactor-tuned front end. OTOH, the SL30 should have a
wideband front end too.
