I am in the process of putting a
titanium bullet with a
15 DB Omni Antenna on the roof, and reuse an old
Netgear WNDR 3300 router. The advantage of this setup is the netgear router has a 2.4 and 5.8 radio, and unlike most repeaters can repeat the wifi on a different channel then the incoming data. Normally you loose 3/4 of the bandwidth repeating the data on the same channel, with this type of setup there is no loss from that, and it is on both the 2.4 and 5.8 ghz. The Iphone 5 (and later) can connect to the 5.8 which I have NEVER seen used in a rv park (mostly due to short range and very poor penetration of structures aka rv's). Inside and outside there is no issues repeating my home wifi from 2.4 to 5.8. If you are slightly technical, DDWRT gives you MANY options of customizing your router.
