FEATURES:
The 6M3 is a light but rugged computer optimized Yagi offering low wind load and great performance for its size.
It will compliment the rest of your antennas and tower system. Quick and easy to assemble, it is also great for mountain
topping, grid expeditions and DXpeditions. The 6M3 features the same machined aluminum mounting blocks and sealed
'T' match block that its big brothers use. The 6M3 is perfect for the ham trying 6 meters for the first time or the the sea-
soned vet who may stack them for improved gain. For the serious 6 meter enthusiast, it provides and effective, inexpen-
sive building block for vertical stacks and MOONBOUNCE arrays. A tuning chart is included for the FM band
