I am very happy with this antenna -- it is very compact when fold together
|
|
|
|
and also quite compact when hung from on a mast. It takes about 5 meters
|
|
|
|
into one direction and about 6 meters up on the mast.
|
|
|
|
|
|
|
|
There is one disadvantage of this antenna: it is only for one frequency, but
|
|
|
|
I usually achieve an SWR of about 1:1.3 instantly when I deploy this antenna
|
|
|
|
at home in my garden.
|
|
|

|
I made my fist QSO with this antenna into Israel (about 2600 km) with a
|
|
|
|
Yaesu FT-891.
|
|
|
|
|
|
|
|
Most of my Winlink sessions from home include this antenna as it takes minimal
|
|
|
|
space and I work a winlink gateway in France or the Netherlands quickly (they
|
|
|
|
respond often within the first three requests).
|
|
|
|
|
|
|
|
I also use [a choke]({{< ref "/equipment/radio-stuff/accessories/homebrew-common-mode-choke/" >}})
|
|
|
|
with the antenna.
