hi, i want an aerial that does both airband and the radarbox.
i was looking at the D-130 Super Discone Antenna.
Specs:
25 to 1300MHz for receiving - 50/144/430/904/1200MHz for transmitting
Specifications
Max. diameter: 84cm
Mast diameter accepted: 25mm to 50mm
Max power rating: 20W (50MHz) / 200W (more than 140MHz)
Length: 1.7m
Would this work on the radarbox, i know it is probably better getting an antenna that is tuned for 1090mhz but would this be better than the suppleid antenna?

It will, no doubt, atcukmatty. I'm using a simlar (Sirio N2000) alternatively to a Wimo 1090. No significant difference.
Expect you to run it outside. Feed it with it with a low loss!!! coax, not to exeed ~ 10-12 meters, and get it up "as high and free" as you can.
Never connect the Airband Scanner in parallel to it (by means of a "T-piece") as that will at least degrade the RBs operation. (by what is called "impedance mismatch") You might use a "power- / signal splitter" to separate both units from each other.
The antenna is designed for outside operation, the default antenna is NOT.

hi atcukmatty
i tried my royal when i first got the box it was very poor compared with the supplied aerial even with the supplied one at about 5 ft off the ground it out performed the discone dramatically
cheers paul
ps now run the wimo 1090 much better

Any wideband/multiband antenna - discone or otherwise is going to be a compromise and is unlikely to outperform an antenna cut for a specific frequency.
