i have a dlink DI-524 wireless router. i was wondering if there was an adapter or some way to modify the plug so that it could be attached to my TV antenna via coaxial cable. what kind of range and bandwith would i be able to expect if antenna were to be mounted above the top of all the trees? if i went all out, would it be at all possable to get a wireless signal to go about twenty-five miles?

If you attach your wireless router's RF connector to your television antenna, you'll be lucky to get any performance at all! It'll probably work worse than using the little stock antenna(s) that came with the unit. Aside from the losses at 2.4GHz through television coax, the impedance mismatch of the antenna and coax will adversely affect performance. In short, it simply won't work! You'll need to use the correct transmission line and antennas, designed for the 2.4GHz band, for it to work. You'll need to use the lowest loss 50 Ohm coax you can afford. Antennas for the 2.4GHz band are readily availble through many of the wireless broadband equipment suppliers. Be prepared to shell out some cash for quality coax, connectors, and antennas! To accomplish a 25 mile shot, at a bare minimum, you'll need absolute line-of-sight between the two locations with no obstructions at all, high-gain parabolic antennas up as high as possible mounted to something very sturdy, and amplification at each end. Even then, you'll be lucky to establish a reliable link at that distance. You'll also be lucky to make a shot like that work without spending several thousands of dollars for decent equipment! Anyway, hope that helps. k_Rob - kk7av
