Suggestion for antenna
 

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,

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.
