New 6 meter 5/8 wave base station antenna shown at the bottom of this page for just $95.99 + shipping.
high performance heavy duty 6 meter antenna was specifically designed to
handle the demanding requirements for repeater use. With a base diameter
of 1-3/4 inches and nearly 1/8 thick high grade 6061 magnesium alloy
aluminum tubing. Its large open frame matching transformer easily handles
1.5 KW of RF power. The wide bandwidth of the 5/8 wave design provides
under 1.5:1 VSWR over the entire 50 to 54 MHz. band with a perfect match at
its tuned frequency. The "virtual mirror" ground plane system
utilizes eight 1/4 wave ground radials to insure the highest efficiency
For years there have been many home brew
projects to construct similar antennas but no high quality versions have been
commercially available until now. This is the perfect antenna for a 6 meter
repeater project or high performance base station installations. Norwalk
Electronics guarantees no single other 6 meter omni directional antenna in
production can outperform this 5/8 wave.
Some comments by recent customers.
I purchased this antenna about a month ago and couldn't be happier. This thing is built like a tank. The tuning steps are clearly marked on the top radiator, and it was right on at 50.125 as set up. No adjustment necessary to get a virtual 1:1 swr. There haven't been many big 6m openings in the last few weeks, but I turned the radio on to 6 this evening and have worked quite a few new grids including XE1KK in EK09 from my home in Wisconsin (EN55). That's over 3000 km on a mediocre opening. Yes, I know a beam would give me more gain, but this thing is sitting in a tripod on the roof of my garage. No rotor, nothing fancy, just a great vertical. I have used it on fm for 6m repeaters as well, and it is broadbanded enough that when I go from 50.125 ssb to 52.830 fm, my swr meter doesn't budge. Great product, KC9JCH.

Tornado 5/8 Wave Base Station Antenna.
$95.99 plus $25.00 US shipping or $50.00 International.
Below is the new 6 Meter Tornado 5/8 wave base antenna. This is an economical alternative to our heavy duty repeater antenna shown above. The main differences are it has fewer radials that are shorter and the vertical section is smaller in diameter. The telescopic sections are held in place by locking screws. Its matching section handles 1KW, is not DC grounded and has slightly less bandwidth. However, the actual performance of this antenna is almost identical to our popular Dominator 6M and at half the cost it's suitable for many installations where severe wind or lightning is not a concern.
