Suggestion for antenna

[Camano viewer]

My GPS is:
48.251802N
-122.447142W
alt. 141 ft.
Can locate antenna on roof. Approximately 25-30 ft. above ground.

I would like a suggestion for a multidirectional antenna. If need be amplifier and rotor is okay.

Any help with this will be appreciated.

Here is the TVFR for the GPS coordinates provided,

30': http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3de1c688a554105d

Given the distance between the north end of Camano Island and the Seattle transmitters as well as the obstructing terrain, I would opt for a full size combination such as an Antennas Direct DB8E + Antennacraft Y10713 + RCA TVPRAMP1R preamplifier. Start with the DB8E facing about 150° and the Y10713 pointed at about 175° per a compass.

The TVPRAMP1R has inputs for both antennas.

Be sure to avoid aiming into nearby trees or structures, including your own.
