I am in a 3 story office bldg on 3rd floor and my cube has a window. Looking for reccommendation on an antenna. Godar, MD ST, etc.?
There are 2 local college jazz stations that I want to receive and a couple others. I hooked up the suppled T antenna and get HD on the one college station but the other stns. that I know have HD won't lock on it. Any suggestions?

  I've been waiting two months for the antenna guy to come to install my four-element Yagi on the roof to see what my little Sony will really do. Tonight, I was told maybe he could get to me in July. Dang!
  
  But ... even with the Yagi a few feet off the ground, I pulled in some great DX tonight. My local NPR outlet, WVIA, started to waver and then, all of a sudden, the digital display lit up with WJCT - from Jacksonville, Fla.
  
  Now, that's a long-haul FM signal to Central Pennsylvania!

    I could put it above the ceiling at work and run some white coax or antenna wire down from it along the wall. Problem is the roof is corrugated galvanized but the walls are just gypsum. Will the yagi work?

      That metal roof won't help at all. You'll be better off with it outside - several feet above that metal. Good luck.

    I had trouble with Austin TX coming in over a local station here. I am south of Houston.
    The Austin NPR was coming in every morning. It is a hard three hour run up the highway to Austin. This is with a circular polarized antenna mounted on a 4' X 4' plywood in the attic.

  "At 63″, the FM dipole supplied with the XDR-F1HD is rather long. Mounted in the clear about 6′ above the floor, resonance occurred below the FM band at 85 MHz. Reducing the effective length with a piece of string as shown optimizes the response for 88–92 MHz. Tie the string so that the horizontal wires are 3″ above the mounting hole. This configuration reduces mismatch loss 0.3 dB at 88 MHz, 1.4 dB at 90 MHz, and 2.0 dB at 92 MHz. To cover 88–108 MHz, use a folded dipole instead. Tilt the antenna to maximize signal strength."

    but the math was too damn hard. Thanks but this won't fly in my office. Boss has already said get rid of the T antenna.

      I hear you. It makes my head swim too. I let others do the math, then they say "Tie up your T" so I do it.
      
      If Hitler, umm, I mean your boss is saying no T, I'd try that Yagi above the ceiling. It's certainly not optimal, and it's going to be more directional, but it's worth a shot. And you already have it. So for the investment in some white coax, you've at least tried it before you spend more money on trying something else.

  I have a real antenna in the attic. But used one of these at the office too. Worked well.
