Re: [HamWAN PSDR] Portland antenna range help?
Attached are two elevation plots. • 47th and Hawthorne The high ground blockage for this path is only 1/2 mile away (in the area of 54th and Belmont). • 45th and Main (the "best case" direction) This looks marginal based on ground terrain, and trees may be a problem getting a straight shot. BawFaw Peak, at 73 miles with a sector antenna pointing away from Portland isn't an option. Steve Ted Timmons wrote on 12/30/18 8:15 PM:
er, forgot the heywhatsthat screenshot.

Thanks Ed and Steve- and Herb offlist. I have to use a protected address for mail so that isn't my QTH. I'm within a few blocks of 4700 SE Hawthorne, which (on hamwan.org) shows as being on the fringe of line-of-sight, hence the need for an onsite test. (see screenshot below). I've also mapped it on heywhatsthat (thanks Ed!), which is promising.
I just don't think we can know for sure without testing it.
Herb- elevation of BawFaw is listed on the Oregon page: http://www.oregonhamwan.com/cell-site-hardware/

Is your station location somewhere other than on your license?
Assuming you can get an antenna on the roof, the terrain looks like a straight shot (using CalTopo), but what it doesn't show are the heights of surrounding buildings.

Hey, is there anyone that is available to check reception at my house, or is there a way I can do it with simple equipment? I'm at risk of being in the shadow of Mt. Tabor. _______________________________________________ PSDR mailing list PSDR@hamwan.org http://mail.hamwan.net/mailman/listinfo/psdr
Eddie, Darcy, and Steve, thank you for your replies. Herb
