Description
Newly developed Linear Phase Shift technology and Direct Joint
structure by three-piece FRP outershell enables antenna to
achieve the following performance:
1. 2m 5/8 wave three-element C-Load and 70cm 5/8 wave
eight-element structure.
2. High performance and high maximum power rating at 2m and
70cm bands.
3. Low VSWR and broader coverage at 2m and 70cm bands.
4. Overlapping three-piece FRP outershell structure is strong
enough to compete with one piece structure.
5. Ring gasket provides perfect waterproofing.
6. Ideally tapered FRP outershell has enough thickness to
withstand strong wind and avoid unwanted QSB.
7. Joint bracket can be fastened securely by special
wrench attached.
8. DC ground structure of the antenna protects transceiver from
high voltage caused by thunder and lightning.
9. Feedpoint connector is being exposed downward at the
bottom of support pipe to make antenna installation or
detachment easier.
10.
With optional 2m/70cm duplexer, two bands can be
transmitted simultaneously, or one band can be transmitted
while simultaneously receiving the other band.
