Folks
We're moving a VHF amateur repeater to a 96' Trylon self supporting
tower. The overwhelming opinion is that our current 210C4 four bay folded
dipole would be too much of a weight and wind load for that tower.
One comment has been the Ringo Ranger. The wind load of the Cushcraft
Ringo Ranger II ARX2B

is 0.5 square feet. The windload of the Sinclar SD214
http://www.sinclairtechnologies.com/catalog/resources/pdf/SD214-HF2P3LDF(D00S-LSABK)-DI.pdf
(newer model to 210C4) is 5.57 square feet. Although the ice area is 17.04
sq ft. The SD214 has a dbd gain of 7.2, dbi of 9.3. The Ringo Ranger has
dbi gain of 7.0. However the coverage plot in rural slightly hilly Alberta
isn't all that much different.
What would be suggestions for an alternative? Comments?
Thanks, Tony
