Model No: 2M8WL
FEATURES:
The 2M8WL provides the user with not just improvements in gain and front to back ratio but also features a robust
boom design, making the antenna capable of handling winds over 100 MPH. The 2M8WLHD features the same highly
reliable, CNC machined, driven element components used on our other VHF and UHF yagis. The boom tapers from 2.5"
in the 23 foot middle section to 1.5" at the rear and front. It is top guyed with dacron cord. A single 2M8WL provides the
gain requirement to make EME contacts with even small 4 yagi stations. It passes the echo test by producing its own
audible echoes even when pointed up with no ground gain! Obviously it is dynamite on Tropo! There's absolutely nothing
else like it.
