Agree that ARRL (American Radio Relay League) has great resources in the Amateur Radio Handbook and their antenna resource books. You can find them in the post library. It even works with 137s and ALE.
I went to every Team house we had in Haiti and you could tell who had the squared-away commo dudes. They were the ones who had their HAM licenses and made regular commo back home to CONUS through HAMs and MARS (who would handle radio-wire interface calls to the house).
You could see it in their antennae and battery/power set ups, from verticle loops to you-name-it. Some teams couldn't make comms to get fed, and they were less than 100 miles away from their B-Teams.
We've got all this high speed real-time push to talk comms from SHF to SATCOM, INMARSAT, and Iridium, yet you can still do discrete dit-dah on low power HF with a good antenna when some command above you pre-empts you or puts you on quiet time.
