A few years ago I added a cheap $15 RCA flat plastic square passive antenna on top of my TT, booster is in the TT.
In North Phoenix at my house I get around 44 channels. LEDs also affected performance, probably from the wired in booster.
The other day I decided to upgrade. Ordered the Vilso 360 Deg motorized and by accident also the Sensar IV batwing (cocktails and Amazon dont mix)
Sensar totally sucked getting only 48 channels, the directional Vilso scored 84 channels......and more if I use the remote and rotate to a channel from a different tower. No interference from LEDs with this one since Im not using the TT booster.
Sensar $48
Vilso $34
