Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
Facebook page, please do.
Yeah - I thought the same about Amazon, but let's not be unkind.
"Antenna Theory and Design" is not something you can casually absorb in a few hours from an e-book, and then credibly launch into a "proposal". Some folk eg. me) have spent a large fraction of their lives untangling antenna theory, and can only get a reasonable grip on a practical subset of it.
From the context of your question, my guess is that you need a general appreciation of the antenna types, and the frequency ranges they best suit. You want to know the constraints of physical size, and cost, and durability. A proposal for a GPS device for a vehicle is going to be very different to one for a newsfeed dish on a field, or a telemetry antenna suited for installation on a satellite. You can gain much of this from the net for free using the generous information on Ham radio enthusiast pages.
Use Google Search for "ARRL". It will lead you into a mess of links where you are bound to get lots of relavent stuff. Try also Wikipedia. Good hunting.
