Jeff,
  You need an antenna with 26.5db gain for the GPS.  The 2480-301 only has 17db gain and will work for the non WAAS 430.  You can install an amplifier inline, but they are expensive and you'd be better off just buying a new antenna.  If you want the tri band antenna, then you need the CI 2480-300.

Question:

 

For the Comat Antenna's:

Will the CI 2480-301 Work with the Upgrade listed below to WAAS for the 430  ?

 

Thanks

Jeff.

Garmin has announced a price increase for WAAS upgrades on the GNS 430/530. Currently the fee is $1500, but effective 1 September 2007,  it will be $2995.  If we lock in an RMA by August 31, 2007 the WAAS upgrade can be completed anytime between now and May 31, 2008 at the current price. To fully integrate this change you will also have to change the antenna (new one comes with the upgrade) and use a predetermined length of RG-400 coax which may or may not already be in your aircraft.

 

As your Garmin Authorized Dealer, Lancair Avionics urges Garmin 430/530 users who have not had their units upgraded to contact us right away to enjoy significant savings on the WAAS upgrade.
