Hi

I just purchased this antenna (Moonraker EVX 5000) on eBay -- it is a trapped HF vertical
for 10m-15-20-40-80m with gain of 3.5db and is 7.30 meters in height.
Their are optional radial rods (10, 15, 20 m) for this antenna., they look like mobile whips.
If I use a full length 1/4-wave counterpoise with this antenna, will it work better
using ground radials or with elevated radials below the antenna base (attached to a mast)?
If I put the antenna at height of 10 to 30 feet ?
Thank you.

Yes,

Moonraker is a UK manufacturer of amateur radio vertical antennas.
Here is their web site:
http://www.moonrakerukltd.com/shop.php?cat_select=12

The EVX5000 currently sells for £ 169.95 .
The EVX-KIT1 is the radial kit for 10, 15 and 20 meter usage and sells for £ 39.95
The EVX-KIT2 is the radial kit for 40 meters and sells for £14.95

ALL 1/4 wave HF vertical antennas requires radials (counterpoise) for proper operation
(Think of this as being the other side of a 1/2 wave dipole that has been rotated 90 degrees).

For a multi-band HF vertical, there needs to be at least one radial for each band of operation.
Whether it is ground mounted or mounted on a mast, the radials will still be required.
