Antenna and filter books

Two new additions to the library arrived in the mail this week thanks to the 2018 ARRL auction.

In this year’s auction, I managed to score a copy of Antenna Theory: Analysis and Design 2nd ed by Constantine Balanis, and Rapid Practical Designs of Active Filters by DE Johnson and JL Hilburn.

Both books are in pretty good condition, especially the Filter book considering that it was published in 1975.  The Antenna Theory textbook still has the 3.5″ disk in the back unopened.

I was hoping to get at least one of the Vibroplex bugs that were also in the auction, but a flurry of last minute bidding drove the price higher than I wanted to pay for them.  Oh well.

Happy with the books I managed to get though.  They’ll be good additions to the library.
