Think of a kid on a swing in the back yard. If you push (and pull) the swing at the same frequency the swing wants to oscillate at on it's own (natural frequency), the excursion will increase and...

I think you have it backwards - the antenna doesn't 'reach out' - it merely collects up whatever reaches IT.
Click on one of the stations in your fool report, and look at the terrain. Those...

From experience, that may be not so good. I've taken the same bearing 20 times and come up with different results most of the time. A magnetic compass, away from ferrous metals like the antenna...

Seems to me that an HBU11 or ANT751 aimed 158 deg. magnetic (the weaker signals) would receive the stronger signals which are exactly 180 degrees opposite just fine. They don't have strong rejection...

From where I sit, and I'm not an RF expert, it appears that the only thing you haven't replaced is the preamp. With 2-edge signals at your location, it's entirely possible that a working amplifier...

Radio Shack has a passive UVSJ-type unit for about $10 or so. My local store had one or two hanging on the hook, and it's all I use to join my DB4e and a portable TV dipole rabbit ears unit that I...

I don't know what the gain figures are for UHF with the 741, but the similar HBU11 is around 5dB +/-, and the DB8e is around 10dB +/- with the two panels facing 180 degrees apart, so I would think...

What antenna is it? Does it have an external balun? Exposed crossover wires that a bird could have sat on and shorted, or maybe too close to start with and temp changes shorted them?
Do a double...

Just to add, in the good old days, before DTV (which was most of my life), multi-path would make for ghost images on the screen. Weak, noisy signals were snowy. Where I grew up, it was both, as a...

The wavelength at 599 MHz is a shade under 20", so I would think moving it up/down even a few inches may make a difference if there's a multipath issue, or it's otherwise experiencing some sort of...

That's in addition to the one you're using, not to replace it. But if you only have room for one antenna on your mast, consider one designed for both H-VHF (channels 7-13) plus UHF reception. Since...
