| Reviews Summary for 20 Meter Backpacker EH Antenna Kit |
|
Reviews: 2
|
Average rating: 1.0/5
|
MSRP: $49.95
|

Description: The Backpacker was developed for those who want an exceptionally good 17 and 20-Meter antennas (more to come) (for use up to 100 Watts) for fixed, mobile, or portable. It just happens to be very small and the antenna of choice for those who enjoy backpacking and QRP, thus the name given to the antenna.

Coax is Your Antenna -- EH is Your Placebo

Time owned: more than 12 months

====== THE COAX IS YOUR ANTENNA ======
======= THE EH IS YOUR PLACEBO =======
"A magnificent device for coaxial cable radiation."
--Hirun P. Maximus, WIAW
EH ANTENNA MAGIC INGREDIENTS
Some level of exoticism in the ingredients and mysticism in the properties of the EH Device are deemed desirable by promoters:
Radiation Resistances
EH Modes
Hz Radiation
Phased Coils
Fields In Phase
Placebo Elements
Kor Radiations
Flipped Orthogonals
Harmonic Radiations
Advanced Jibberishian Mathematics
Unlikely ingredients such as the baobab fruit were added to the active elements, along with unspecified roots found in swamps which have remarkable effects as the dielectrics for matching coils.
One example of the magical properties and ingredients approach is the Kickapoo EH Antenna, a product of the Kickapoo EH Company of Frestonia (completely unrelated to the Kickapoo Indian tribe of Oklahoma), supposedly based on an ancient Native American EH Vertical Totum Dipole design. The EH Totum Pole was the inspiration for Al Capp's "Kickapoo Joy Juice," featured in the comic strip, "Li'l Abner".
EH Antenna promotions are part of the tradition of timeless herbal wisdom, famous among travelling doctors, as seen on the popular TV show "Technology Of The Old West". Just about any scientific discovery, phase differential, or exotic micro organism can be used as a key ingredient in a patent medicine or magic antenna.
Ham operators are invited to invoke the power of electromagnetism to heal their ailments. In the 20th century, electricity and radio were scientific advances that found their way into patent medicine advertising, especially after Luigi Galvani showed that electricity influenced the muscles when an EH Antenna was used by the operator to stimulate the brain of frogs.
Devices meant to electrify the human body have been long sold as a miraculous benefit with proven enhancement results; EH Antennas are purported to attract Single Point Energy which makes the body more conductive and thus your skywave ionosphere propagates better. Albert Abrams was another well known practitioner of EH field theory, claiming the ability to diagnose and treat diseases over long distances by radio, using only a simple Stacked Six Over Six Element EH Antenna Crossed Field Array Hula Loop, and simultaneously maintaining his QRP transcendental contact with pure CW. It has been reported that the signal was so finely matched in phase with the 377 ohm radiation resistance of the universal ether, that it can still be heard on 40 meters as a Long Delayed Echo (but only by highly skilled operators using Coherent EH Antennas).
THE EH "IN-PHASE PLACEBO EFFECT"
"The physician's belief in the treatment and the patient's faith in the physician exert a mutually reinforcing effect, just like the E field and the H field of an antenna; the result is a powerful remedy that is almost guaranteed to produce an improvement and sometimes a cure." -- Petr Skrabanek and James McCormick, "Follies and Fallacies in Medicine", p. 13.
The EH In-Phase Placebo Effect is the measurable, observable, or felt improvement in general health and well-being of the operator, combined with an increase in DX angle of feedline radiation. This effect is believed by many operators to be due to the placebo itself in some mysterious way, but has been scientifically proven to be due to the careful EH Mode phase alignment of the electromagnetic fields in the near field of the antenna as they interact with the human brain of the operator.
Researchers and medical doctors sometimes give placebos to patients and contest operators. Anecdotal evidence for the placebo effect is garnered in this way. Those who believe there is scientific evidence for the placebo effect point to clinical studies of ham radio operators, many of which use a control group treated with a placebo such as an EH Antenna for 20 meters. Why an inert substance, or a fake surgery or therapy, would be effective is not known. But the psychological theory is that it's all in your mind; some believe the placebo effect is due to a belief in the treatment or to a subjective feeling of improvement due to the mind's interaction with the electromagnetic field's radiation resistance when it is in the EH Mode.

PLACEBO DEFINED
Definition: pla·ce·bo
Pronunciation: pl&-'sE-(")bO
Function: noun
Etymology: Latin, I shall please
1 a : a usually pharmacologically inert preparation or antenna prescribed more for the mental relief of the patient than for its actual effect on a DX disorder
1 b : an inert or innocuous substance used especially in controlled experiments testing the efficacy of another device or antenna
2 : something tending to soothe
Definition: Placebo Effect
Function: noun
: improvement in the condition of a patient or operator that occurs in response to antenna coaxial feedline radiation treatment but cannot be considered due to the specific treatment used
A placebo (Latin for "I shall please") is a device, medication, or treatment believed by the administrator of the treatment to be inert or innocuous, such as a dummy load, but it is in effect an actual antenna in the mind of the operator.

I spent the $$ to get one of these kits despite all the rumblings about breaking the laws of physics, being a hoax, etc.
The 1st one I got turned out to be defective, according to the mfr., and I returned the kit for replacement. Excellent customer service.
The 2nd one went together more smoothly. Same documentation (which isn't bad) and clever packaging. Maybe the assembly went so well because I had built the one earlier...
Anyway, it does show a good SWR on the 20 meter band, or at least most of it. So the Q is good, it's not a dummy load in any conventional sense. You can't check resonance with an SWR analyzer though (so says the factory, but without an explanation); you have to use the rig. And, a tuner is verboten, too, but it's also unneeded.
I did not witness any feedline radiation, and did not use the gimmicky tuning shield nor did I connect a ground. I wanted the unit to go portable with me as a true backpack antenna; throw a line up into a tree, hoist up the antenna, and get on the air.
Well, all except the last part happened. The antenna transports easily and can be put up quickly. It just doesn't radiate worth a hoot. I guess it's about what you'd expect from an antenna this small, for this band.
An end-fed sloper would work (and does work) much better, costs less, and is lighter. Sorry, Ted, but this EH Backpacker is really not worth the money.
