DIY Outdoor Wi-Lan enclosure

Dan wanted a true outside enclosure for his Wi-Lan equipment that could withstand the forces of nature where he lives.

He writes:

This box will house my proprietary Wi-Lan HP45-24 radio unit and set as a client, a 2.4ghz 500mw HyperLink Amplifier connected to a Linksys WRT54G with a third party firmware and set as an access point, the Wi-Lan HP45-24 radio will be the main link back to my base radio.

The whole idea of this enclosure is to be as “modular†as possible, i.e. if the PSU blows-up i can simply remove the PSU and replace it, OR if i need to relocate the whole box, i can simply unscrew all the antenna and take it away with me.

The referenced article says:

My friend is very concern about my idea and he told me that the socket is dangerous as it is exposed and not water proof, i told him that the socket is secured enough because the matching lead that will goes into it is secured and water tight plus i will put some kind of rubber shielding around it.

It is recommended to treat all connections with dielectric grease before attaching the wires. The dielectric grease is a non-conducting grease that will not cause short circuit across the connector leads, and will fill the air gaps to prevent them from getting water in case of rain. The grease repeals the water and will extend the life of the contacts. Fill the connector with enough grease - the metal leads will displace the grease where required and will make a good metal to metal contact.

The easiest dielectric grease to find is the the one used for car tune-ups (spark plugs, etc.). Check your auto-parts. If you are going to use a lot, you can check the company that makes the grease for the car making companies:

You can place a small size order from their small volume distributor:

I ordered from them a 17oz can of NyoGel 760G for shielding some ethernet data drops from the corroding sanitizating products at my work (about $60, but it yields a lot). They may recommend another one for you application. I use a one of the syringes used to dispense oral medicines to babies to pull the grease out of the can and apply into the connectors.

Finally, for even further protection, consider placing some Liquid Tape® outside of the connection. You can buy it at Home Depot. A good trick is to place a thin wire outside the connector before applying the Liquid Tape for peeling the rubber up when needed by pulling the wire.
