Cisco Aironet AP34x External Antenna Modification Procedure - add RF connectors to a very robust Access Point. Very simple modification
SMC-2632 802.11 PCMCIA external antenna modification.
Add a SMA connector to your SMC-2632 transciever.
DWL-650 External Antenna Mod Will Rachelson, a participant of Seattlewireless, documented a method to add a coax pigtail to the dwl-650 PCMCIA 802.11 transceiver.
Compaq WL100 External Antenna Mod and removal of diversity, by Paul Marsh, a participant of FRARS group in the UK. Minimal instructions, but enough to get the job done.
AT&T/NCR Wavelan
2Mbps/10Mbps Wireless Ethernet Interface. We are using some of the DEC
RoamAbout PCMCIA units.
Add a SMC Female RF connector to your wavelan transceiver module.
OpenAP Project - A how-to on squeezing Linux into Access Points that utilize the Eumitcom WL11000SA-N board. The following access points: US Robotics (USR2450), SMC EZconnect(2652W), Addtron(AWS-100) can be converted.
The Slovienen design of BPSK transceivers
shall appear here shortly. I have entered most of this into schematic
capture software (working from electronically scanned pencil drawings.)
I have also started to convert the 2.3Ghz design from all discreet components
into a design that will utilize the RF Monolithic chipset for various portions
of the design.
Antenna Systems
Low Power 5dBi Vertical Collinear Antenna
Another design by Brian Oblivion and Cpt. Kaboom, much easier to construct than the 6 dBi antenna.
6 dBi Omni-directional Antenna Plans
This is a design that Brian Oblivion and Cpt. Kaboom conjoured for external
2.4Ghz 802.11 Access Points or STAs.
Discone An interesting discone design, very similiar to the Ramsey Electronics 2.4Ghz discone kit. Radiation pattern is no better than a common dipole.
Sectored Patch Antenna Good, solid construction of a Sector/Panel type mast mounted antenna.
Helical directional Antenna Plans This antenna is most efficient when used with other circularly polarized antennae. Expect a 3dB loss when using in conjunction with a vertically or horizontally polarized antenna.
15dBi SeattleWireless Yagi 'cigar' line yagi, easy to construct.
