If you want quiet outdoor antenna for FM band, go to an folded dipole or full wave loop, with loop you can null noises from neighbours.

Build about 102cm long horisontal and 51cm tall vertical parts, feed from center of 51cm part.
No baluns or anything needed.

Measurements are from my head, might check them with calculator, but they are close.


Like this:

Use some PVC etc pipe to hold it up, bend it from 4mm aluminium tube or wire.

For mounting it to the PVC pipe, drill hole about 25.5cm from top, feed coax truh it and solder/crimp it to the wire/tube using you favorite method.

Pull that loop wire/tube near PVC tube and use some zipties/tape to secure it to the side of pipe.

If you want one vertical, just turn it so that 102cm part is up, feed from middle of 51cm part.

I have another amplified, portable aerial that I sometimes use, is based on an old Elektor design called the "Omega Aerial". It's performance is really good, but it's not as convenient as it's a loop design. It's sometimes useful to null out directional interference, however, as it's very directional.

Thats a quite classic one!

It is. The only (minor) problem with it is that the FET can be killed by static. It also runs warm because of the low value emitter resistor for the 2219. We had some snow about 2 weeks ago, and the aerial was covered with snow and ice in the morning, but the little tubular can that contains the amplifier was clear of snow!

Old modifield was like Vishay +100Mohm thickfilm resistor from fet gate to ground, and that 1Mohm resistor was something "little bit lower value", dont remember what.
