 TOWER - Custom trailer for AB577 portable towers
- Custom trailer to carry one or two AB577 masts (trailer customized by W4MY). The picture shows how everything fits - it is not strapped down for transport, but you can see how it fits two masts and two big job boxes for all the parts and tools, with space left over. I placed my antennas down the middle, on top of two boxes.
(Sorry, the masts are not included, they have been sold.)
Trailer is in good condition, tires are excellent, it pulls smooth and straight. It is titled. Takes 1 7/8" ball. More pictures available.
