And so was born the Mini-Whip Slimline. It is now much easier to clamp the entire inside or outside with standard 3/4 plastic brackets or clamps.
The concept remains the same, only the prints are adapted to fit directly into the tube. Internally it is 3/4" or 16mm. The Antenna plate is 100mm x 16mm copper (singe sided) . Capacitors are 220nF or 470nF (MKM or caramic).

+ antenna-part
in a
piece of electrical PVC pipe from
3/4 " or 16mm,
(from the Hobby Market).
If the BNC connector does NOT fit in the tube, then it may be better to left it out, and the cable to the power PCB can be soldered directly on the mainbord.
Do not forget, feed the cable through a hole (6mm) in the sealing cap before soldering him to the main PCB.

The power
PCB can also
fits in a piece of
PVC pipe
(maybe wihthout some BNC connecter) , or in a
square alluminium tube. You can wind
a piece aluminium foil arround the pipe, and
ground it to the cable shield.
Again, the BNC
connector can be omitted
if this is required, and the cable
can be soldered
directly .

The
whole part
can fits in a piece
of electrical
PVC tube
of 3/4"
or 16 mm . The
sealing caps
are not
present here on the main PCB.
Wanna see a test of this antenna, look on my website HF Mini Whip Antenne.

Enhanced Mini-Whip antenna (0-30 MHz)
New structure
The Mini Whip antenna (see my previous article Mini-Whip Antenna 2016 ) are already made in countless designs and implementations. However, in the practical implementation, it is not always easy to find suitable housing for (outside) assembly. These are sometimes jars, boxes, tubes and other peculiar housings, which then still have to be waterproof. What if we turn the matter? I came up with the idea of the whole to miniaturize some more, so we can use a simpler construction : as a piece of electrical PVC pipe 3/4 " (16 mm) with two sealing caps (for chair legs), where all the Mini Whip retracted can become.And so was born the Mini-Whip Slimline. It is now much easier to clamp the entire inside or outside with standard 3/4 plastic brackets or clamps.
The concept remains the same, only the prints are adapted to fit directly into the tube. Internally it is 3/4" or 16mm. The Antenna plate is 100mm x 16mm copper (singe sided) . Capacitors are 220nF or 470nF (MKM or caramic).
