I enjoy antennas and want to understand them better. One tool for understanding antennas are antenna books. For some one or two is enough but I have many. The same story may be rewritten many times but one account may lead to that aha moment. I find some at good prices used at Amazon or EBay. I was not used to buying used books but they are fine. Be careful buying and check around. A retail seller might be reasonable. Universal Radio has a good listing
. I setup a Google+ community for Antenna Books at
BTW I find Successful Wire Antennas Edited by Ian Poole G3YWX. to be well done, complete and up to date. I highly recommend it.
