cant complain.....but

[CtrlAltElite]

I have have 2x Wingard antennas ($35 home depot) one being run to main tv (30 stations, 22-23 watchable) from attic, other is on j pole on garage going to bedroom (43 stations, 33-35 watchable) My question is, if I upgrade both to http://dennysantennaservice.com/ez_hd_tv_Antenna.html will this increase my channel lineup and stability?
