Aerial-51 was created for the following reasons:
- A belief that with antennas, "HEIGHT IS
MIGHT"
- Keeping an antenna light enables erecting it much
higher
- Modern lightweight materials are available for building
antennas:
- Very tall, lightweight telescoping
fiberglass poles
- Thin,
CopperWeld wire (lightweight but very strong)
- Strong lightweight rope (Kevlar, Dyneema, PVDF, etc.)
- Lightweight insulators (Polyethelin, Plexiglas, FR4, etc.)
but . . .
- Currently most companies designing and building wire antennas are still building them just like they built them in the
1950's:
HEAVY AS A TANK!
- Unfortunately most text books are still teaching the same consturction technique as used in the
1950's.
- Amateur radio operators, unfamiliar with the construction techniques of these new materials, continue to home brew antennas as if they were preparing
for World War II.
- Then in portable operations, they often erect these heavy monsters just 15 to 20 feet high and wonder why their signal is so poor.
(duh)
Aerial-51 represents a
modern, lightweight approach
to antenna construction.
I live on a mountain side in central Germany in the region of Main-Spessart.
I have an antenna test field located behind my house, farther up the mountain, well hidden by trees.
When visitors ask me where my antennas are, I point up the mountain and say "Outdair Sumwear". In the meantime that's the name I
have given my antenna test field. :-)
All Aerial-51 antennas come from Outdair Sumwear.
