We live on several acres in a small mountain range, with Internet access via a DLink DSL2640B which includes a 802.11b/g AP. DSL works much better with this unit than the preceding modem from the phone co, so we'd prefer to keep it. Wifi works OK inside the house with our MacBook Pro and an Apple TV.
We've recently acquired an RV which is parked about 250' (76 m) from the house, at a higher elevation which gives line-of-sight between the roof of the house and the RV's front seats. When in the RV, the laptop doesn't pick up the DSL2640B, which is on the other side of the house at the lowest level.
Company coming for the holidays will banish us hosts to the RV. We would like to extend the Wifi range to be able to use the laptop in the bedroom which is in the back of the RV (two partial intervening walls with doorways in them).
In reading some posts on this site I've gotten the idea that a more capable antenna should be tried before an amplifier/booster. I think the best start would be to mount an outdoor antenna at the highest peak of our roof, which is close to straight above the AP. Maybe 25, for sure 30 feet of cable would be sufficient between them. We're near the California coast and have heard one clap of thunder in 23 years here, so I'm not minded to bother with entry grounding, isolator barrels, and such.
The DLink unit has one antenna that can be unscrewed, presumably RP SMA. Since we'd like the Wifi to continue to work in the house, the antenna probably doesn't want to be very directional. (Wish the AP had more than one antenna connector! We could upgrade to a DSL2740B which adds 802.11N and a second antenna connection.)
What I would like from this forum is recommendations for antenna(e) and cable(s) for the first stage of upgrade. No UGG boots needed :-)
Thanks for replying. I had only thought of upgrading the base station (router) antenna. Which is the "receiving end"?
Lacking any other recommendation, I'm thinking of the Alfa 15dB 48" antenna for the silly reason that our RV is an Alfa (almost certainly a different company :-) Does anyone have anything against the Alfa antenna, or know of a better one?
I believe that the best practice in a situation like this is to leave the AP antenna stock and put the gain antenna on the far end of the link. In this case, the RV. changing the AP antenna affects all users, and may affect the neighbors. a directional antenna on your RV should affect only your system.
