The HD Stacker TV Antenna design

140" of performance in a 70" antenna

Hd Stacker antenna design

It's all about surface area. The more surface area an antenna has the more signal it will capture. Stacking one antenna above the other allowed us to design an antenna less than 6 feet long that performs like it's 12 feet long. This design also provides a stable and strong mount that will withstand strong winds, ice and snow. The zinc plated steel U-bolts and locking jaws will insure the Stacker won't twist and turn in the wind.

The antenna has been precisely frequency tuned and field test to insure proper phasing and spacing. The two antennas actually work together providing the best possible signal reception.

The Stacker design drastically reduces antenna length and width while maintaining the same antenna overall height, without giving up the performance of a true long range antenna.

The HD Stacker antenna VS. Channel Master 3020 antenna.

I've included an example from Bob in Newberg, OR. The HD Stacker will perform as good or better than antennas twice its size.

Hd Stacker performance VS. Channel Master 3020 antenna

Bob from Newberg, Oregon reports his results after switching from a 12' 6" long antenna to the 5' 10" long HD Stacker antenna.

I just wanted to let you know that the HD Stacker arrived on Friday and I installed it on Saturday.  I did a before/after check of signal strength (using TV signal strength readout) and saw an improvement on all channels!  
My main goal was to improve reception on Channel 6 (RF 40) which is our local CBS station.  The reason: I'm a big fan of the NCAA basketball March Madness tournament which is broadcast on CBS.  Using the signal strength indicator on my TV, I saw the level change from 4 bars (with my old antenna) to 7 bars!  I'm not sure what a bar equates to in micro volts/meter but it made reception much more solid.
I'll attach a document showing the improvement noted with the new antenna for all channels.
Assembly of the HD Stacker went well and all parts were there in the shipment.  Construction quality of all antenna sections was very good.  I really liked the compact nature of the Stacker compared to the 12-foot behemoth it replaced!
Next step: replace the old RG59 coax with new RG6, as recommended (just ordered that tonight).
Thanks for your support and for the nice antenna design.
