I suggest the stack matches at the tower base and stand up dog house for
them. Thus inside storage of matches and the equalizing coaxial cables
(100's of feet of hardline) so they are not on the tower, and protected
from the weather. Then a single coax and control cable for each band
stack to the shack. Having multiple radios on the same band at the same
time on the same tower is probably not possible at HF. Having each
band's stack on a single run tower to shack permits SO2R or M/M
operations on separate bands with adequate filtering and such is
available off the shelf.

Each of the 4 towers is going to have a mono band stack of either 2 or 3 six element yagis plus 5 antennas for 80 and 160 so I kind of wanted a feed from each antenna Sent from my iPhoneOn Feb 13, 2017, at 11:02 AM, Ed Sawyer <sawyered@earthlink.net> wrote: John. Most of us would run 2 radios worth of hard line to a central spot and then have a 2 x 6 - 2 x 10 antenna switch that feed all the antennas in the field. This cuts the feed line expense substantially. Are you sure you need 5,000 feet? Sounds to me more like 2000 - 2500ft in the conventional switched configuration. My 2 x 8 switch happens to be at Tower 1 as the systems evolved over time (300 ft from the shack). Its another 150ft to Tower 2. 300 ft to the 160M array. Beverages and receive antennas are another story. 73 Ed N1UR _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk_______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk |
