Thanks Grahame. Been thinking about making a collinear antenna for awhile. Wasn't sure of the formula. Looks like a New Year's project to try.

Have a left over length of LMR400 from the original ADS-B antenna installation that will come in handy.

Will be interesting to see what improvement the LMR400 over the RG58 feed does to your setup.

Happy Christmas,
