Good Antenna  Time owned: 3 to 6 months
Hi OMs,

I'm using this antenna now for several month and I don't regret buying it. Assembling is "classic" as you can see in the manual (pdf at the homepage). Optibeam 7-3 seems to be more comfortable for assembling but the price is significant higher. Here are some facts:
- 6 active fullsize elements: 2 element for 20m, 2 element for 15m and 2 element for 10m. - No traps, no powerlimits (except possible balun) - Single feedline - Direct 50ohm feed ( JP Current Choke-H 1:1 balun is recommended) - All parts are from aluminium or rustproof steel - Antenna can be used as a dipole on 17m band (SWR will be as high as 3) - On 12m band antenna gives 3-4dB gain and 10dB F/B ratio, but SWR is high, about 5. - Mast clamp fits 80mm to 45mm

Assembling(Adjustment) was no problem. Assembling document tells you the right length ... values are ok.

This Antenna (height at 13,5-14,0 Meter) brings the world to me ... ;0).
