Hastings Wireless: Antenna Tests


2004 Jul 20 - Brian Kloppenborg

We finally got out in the 98 F weather and started testing on our equiptment. We used a Laptop with a Netgear MA401 V2 PCMCIA card for the mobile point and a DWL-900AP+ for the stationary point. We mounted everything to a tripod for testing. A one meter patch cable made from LMR-400 was used.
