Think of it like a net, the larger the net, the more of the signal you are receiving. However, if your net is larger your net, the more potential there is to pickup the background noise and whatnot, especially when you move past 1 wavelength.
This can also un-match the antenna to the designed frequency and this will introduce a much higher SWR which can permanently damage the front end of the radio making it totally useless sometimes. But hey it looks cool cause the mil guys do it. Heber there radios are designed to tolerate much higher swr and when the blow the front end they just swap it out with antihero from stores ad have the original fixed. YMMV
