Michael, low cost PTFE/woven glass base materials are TLC-30 (DK 3.0), TLC-32 (DK 3.2), and RF-35 (DK 3.5) from Taconic. All of them are used at the frequency range you described. Please contact us off-line to discuss further.

Intentions are to emphasize microstrip matching at higher frequencies (2ghz) and lumped component matching at lower frequencies (500mhz). Basically, what works the best and is cheap.
