Congratulations, Tram-Browning Corporation, for having what I can genuinely say is the least usable website I’ve encountered in months.
Click their site, you receive a big splash image and links to open one page of their catalog in a new window. It opens a PDF.
There is no single page catalog PDF.
There is no index.
There is no search.
There is no actual usability.
ARRRGHHH!!! If you’ll excuse me, I’ll be off straightening out a coat hanger and soldering it to an SO-239; this is going to be more productive than trying to use their catalog to order an antenna.
