I've been reading about these and am intrigued.

These antennas are often mounted in a sloping configuration, but
how steep can the angle be? I'm sure the steepness of the angle
is going to effect the antenna's radiation pattern, but will
how? Does it cause the antenna to become highly directional as
the angle increases?

How do these antennas perform in relatively noisy environments?
I've read that they're relatively slow to pick up local noise,
but I'd like to hear about some people's first hand experiences
with them.

Are these antennas inevitably eyesores to those philistines who
don't appreciate the beauty of a good antenna? Is there a way to
make them less conspicuous?

Sloping the antenna is an attempt to cause it to be more
broadband. This is not much help on reception but allows the
antenna to be used over a wider range of frequencies on transmit
due to a reduction in VSWR.

The termination resistor causes the antenna to be lossy and helps
with the VSWR aspect on transmit but is no help on reception.

The matching section is also a wast of time on receive. You are
better off using a broadband transformer.

There is nothing great about this antenna for reception. You are
better off using a folded dipole.

I would disregard everything written above. The antenna is very
quiet for receive.

I found it to be 'quiet' because it really didn't receive very well.

I built two and chucked 'em both soon after.

I disregard everything Dave writes. If he could pay attention, which
unfortunately he can't he would recognize that the T2FD is basically a
folded dipole with modifications so it will load up on transmit. Those
modifications are a waste of time on receive and the reasons given are
the rational unlike the advice given by the short attention span guy.

As DxAce found out it will not pick up the signal levels his current
fairly long horizontal wires will with or without the T2FD
modifications.
