Looking through my recent QST a small ad from Technical Antennas caught my attention. They offer the following two mesh dishes, each with a broadband feed. $149 and $189. Horizontal or vertical mount, 100 watts max, N connector. Here is the info and links.
Gain: 14dB - 25 dBi
Operating Freq: 600-6500 MHz
