Hello, I'm JP1QEC. (phone Akira, CW handle: MOT), living in Saitama, Japan. My name is Akira MOTohashi.  [*YouTube videos*]. And I use ABU as a handle on twitter and FaceBook. I am a member of SKCC # 14687. I am joining SOTA program as an activator on 7,14,18,21cheeky.

Rigs for portable are FT-817ND,DJ-G7,MX-21S, KX2. And antennas for portable (homebrew) are Full-size Inverted V wire Dipole: 40m,17m,15m,6m, and GroundBeam QEC model on 30m, 20m, 17m, 15m. GroudBeam-QEC antenna is my original one. On UHF Band, I enjoy 1.2GHz with homebrew 6ele.Yagi.

< GB-QEC antenna >

I will introduce a new antenna for mountain use.
I named this antenna like GroundBeam-QEC.  GB-QEC for short.
Because this is an antenna array of 1/4 lambda.
I always use 2 elements, but element number can increase.
As a result of a simulation using MMANA-GAL, Front gain was 3-4dBi and F/B ratio was 8-10dB and elevation angle was 25 deg.
The features of this antenna is as follows. 


(1) This is a wire antenna, so very light weight.
(2)Very compactable because of the wire.
(3)This antenna is shorter than EFHW.
(4)Very brief structure.
(5)electrical feeding impedance is about 50 ohm. So, can connect directly coax.
(6)Have a beam pattern.

In case of 2 element.

GardenBeam is an old name. Now is GroundBeam.
