A few weeks ago, I finally put up my T2FD. I went with one 131.5 ft long, so cut for 2500 kHz and up. I'm using a 12:1 balun and feeding it with 100 ft of RG6-U 75 ohm coax. The center termination resistor is 800 ohms.
The high end is perhaps 50 ft up, the low end about 20 ft, and it slopes to the south. Not my preferred orientation, but you take what the trees give you.
I'm really amazed with the reception. While the signal is generally an S unit or two lower than that from one of my dedicated dipoles (for the 90, 60, 48 and 43 meter bands), the noise is much less, hence a much better signal to noise ratio. And it works everywhere on HF, I don't need to keep flipping between antennas.
Performance on the high end of the MW band is also excellent (as compared to an approximately 500 ft long random wire). Performance is much worse on the low end, as expected.
I'm really pleased with the results. I'm actually very close to removing the antennas switch, and just connecting this as my only antenna. It's that good.
