Dimensions and design
It is much smaller than a Beverage and can fit on a limited property.
Construction and tuning
Step 1
Install two separated supports.
Step 2
Run a horizontal wire between their tops.
Step 3
Connect one end through a resistor to ground.
Step 4
Install a transformer at the other end.
Step 5
Provide two comparable grounds.
Step 6
Orient the antenna for the desired direction.
Advantages
- More compact than a Beverage.
- Directional.
- Simple construction.
- Useful on lower bands.
Limitations
- Strongly dependent on grounding.
- Weak signal.
- Pattern affected by soil.
- Not suitable for transmission.
History and origin
The EWE was popularized as a compact alternative to the Beverage for 160 and 80 metre reception.
Safety
Vertical wires and grounds require surge and lightning protection.
