MFJ has introduced a new discone antenna: the MFJ-1868.
It is designed to receive radio signals from 25 - 1300 MHz and to transmit from 50 - 1300 MHz (up till 200 Watts RF power). Interesting because it covers 6m, 4m, 2m, 70cm and the 23 cm band.
A discone antenna is omnidirectional, vertically polarized and has a rather narrow radiation pattern in the horizontal plane. This makes the antenna sensitive in the direction of the horizon. SWR remains below 1:2 for the 50...1300 MHz frequency range.
Interesting if you do not want your garden covered with lots of antennes.
The MFJ-1868 has a vertical whip affixed to the centre in order to extend the low frequency response.
Price of this antenna: appr. $70
