The Mikrotik R5H is a 320mW 802.11a miniPCI card operating in the 5GHz band. Air-Stream real world comparisons against the venerable XR5 shows that the R5H performs consistently better over long distance links in Mikrotik Routerboards. As a dedicated 5GHz card (as opposed to a dual-band card) it has excellent receive sensitivity all the way up to 54 Mbps and the output power does not drop off dramatically in the higehr bit rates as is typical of dual-band cards.
Note: This product has now reached EOL and Mikrotik plans to replace it with the R5nH. Since the R5H have proven their reliability Air-Stream has secured a supply of these excellent cards for future replacements and upgrades.
