High performance HF-WARC-VHF 6-Band STACK antenna 6B-15-5

Six-Band HF - VHF - WARC antenna 15 elements for 20m, 17m, 15m, 12m, 10m and 6m band with central wide spaced elements that can fit in antenna towers up to 1m wide. Specially designed for rotary towers and for antenna stacks.

Configuration per band 222234:

6-Band-HF-VHF-Yagi-Antenna-PA141821242850-15-5-antennas-amplifiers

HF 6-Band antenna 6B-15-5 can fit in the middle of rotary towers or on the top. We propose tower not wider than 0.8 m. It will perfectly fit with about 12 cm space from all elements to tower. Ideal for Six-Band stack.
 
Antenna uses common feed line. Input power limited by feed line only. Very low SWR, excelent gain. Wind survival speed 170 km/h.

Strong and sturdy initial diameters ensure high resistance to high wind and snow. 
Rugged construction will enable long-life operation in all weather condition.
 
We produce two versions of antenna:
 
1. Six-band antenna 6B-15-5 to be used alone. 6-Band antenna have best SWR across all bands 
 
2. Six-band antenna 6B-15-5-STACK to be used in stack. Small difference is in element lengths that will improve SWR on all bands. 6-band antenna in stack will have best possible SWR as UPPER, LOWER and in STACK.
