I am helping a friend set up an antenna system for OTA. Existing antenna is at 40' and is V/U combo. I have attached the url of my tvfool readout but this is what is happening. I have the existing antenna directed to north for pickup of 8 (CBS) and 13 (NBC). CBS is about 30 miles and it comes in fine somehow 13 won't com in anymore. I have added a Antenna Direct DB4 positioned to due west. THese two antennas are combined with a UVSJ. The UHF antenna gets these: real ch 50 which is a repeated signal of KTTC out of Rochester MN (low power) but comes in fine. FOX 25 come in fine along with WHLA 31 public TV. THe kicker is I can't get any signal for WXOW 19. 19, 25, 31 and KTTC's repeater are on the same tower that is visible and is only 6 miles away. 2 questions: Why am I not being able to get any signal from WXOW and the old existing antenna is pretty old but it was able to receive WEAE out of Eau CLaire but not anymore. Do you think a VHF high band is in order to replace the old existing antenna? The no 19 signal is baffling me. Any suggestions are appreciated. Thanks Joe Seem I can't post the URl for my tvfool readout. Parameters are: ZIP 54601 height of antenna is 40'
