The perspective of that Street View picture distorts just how tall the 150 foot tower is relative to the surrounding trees. Line-of-sight is clear in all directions. This tower has been used for commercial microwave shots to locations "over town" (what we Vashonites call any land area off of the Island). Both Verizon and AT&T are tenants of this tower. 73, Daniel K7DGL On Mon, Mar 27, 2017 at 12:34 PM, Tom Hayward <tom@tomh.us> wrote:
HamWAN will entertain all offers for free tower space with good line-of-sight coverage.
Firstly, have you tried to receive HamWAN signal on Vashon from one of the nearby sites (Gold Mountain, Tiger Mountain, Baldi)? Looks like most of the island should get a good signal from at least one of those sites as long as you can find a clearing through the trees. You could deploy something from our Client Hardware recommendations yourself to get your EOC online: https://hamwan.org/Standards/Component%20Engineering/ Client%20Hardware.html
Via Street View, I don't see much for tower space at Station 55. How much tower space could they provide for HamWAN above tree level? https://goo.gl/maps/YE827UmUdQK2

As long as others are suggesting options, Vashon should also be considered. VashonBePrepared (.org) is local Citizen Corp Council and a very active coalition of about a dozen disaster preparedness groups.
One of our partners, Vashon Island Fire & Rescue (King County Fire District 13) has a nice tower at their station 55 (www.vifr.org, 10020 SW Bank Road, Vashon 98070, 47°26'53.46"N, 122°27'45.98"W), that has battery & generator backup power & *might* have space available for a HamWan node. Station 55 is the main fire station for the island and is where Vashon's EOC (VashonEOC.org) is located. (We're planning a move and redesign of our EOC later this year.) There are an additional 4 fire stations that we'd love to have connections to, but they are less critical.

An additional site that is also near the crest of the island is near another partner, Voice of Vashon (VoiceOfVashon.org, 47°25'7.53"N, 122°27'50.65"W).
There also a number of commercial broadcast stations on Vashon that might conceivably be approached for antenna space if interference wasn't a problem for us or them.
Vashon is connected to the mainland via three fiber optic lines (2 in the same conduit) and much of the island's internet service is on overhead lines that aren't very robust. We'd love to have additional secondary ways to connect to the world after an earthquake. We also have an active HAM club and a system of WinLink stations, but they are low bandwidth unfortunately.
If a site on Vashon makes sense to the HamWan community, we can provide limited funding and possibly ongoing volunteer help, depending on what would be helpful. I can set up a meeting or connect you to others here as needed.
