The weather is getting better and summer is almost here. Yes it is time to start homebrewing some kind of a ham antenna. It does not matter whether it is a moxon, quad or dipole antenna. The one main tool you should have is a good swr analyzer. You will find that it is an invaluable tool for your ham shack. During the building process it will come in quite handy.
Mfj and Rig Xpert are probably two of the most popular swr analyzers out there. You can buy new with Amazon or Used with Ebay. Of course you can also find new items at Ebay as well. My best advise is to check out Eham.net for reviews on all swr analyzer and check out the seller for good or bad reviews. This way you will get the best deal and not a boat anchor.
