A common problem with qrp transceivers is a weak frontend . Most end fed antennas use low pass tuners causing high stress due to strong signals coming from BC stations .
The High pas tuner used here helps to reduce these problems. Put 19 turns 1mm transformer wire on a T130-6 torroid to form a 4.8 uH coil. The trimmer used is a 60pF compression type set to about 25pF . Put a 3.3K resistor between the antenna connector and the ground of the coax connector and tune the trimmer for resonance at 14.180 MHz.for ssb or 14.030 MHz for CW. Keep in mind that a thin antenna wire has a higher Z. Use hot glue to fix the toroid and the trimmer.
After tuning the unit, connect the half Lambda wire ( 10.15m PVC covered stranded copper wire) and cut it for lowest swr. A 1:1.2 swr is easily obtained with this unit. The cabinet is a PVC type G302 made by Velleman. Every end fed / vertical needs some kind of counterpoise to pusch against and in this case that's the coax , so don't forget a line choke near to your transceiver.

Fiat Panda
From Wikipedia, the free encyclopedia
"The Fiat Panda is a city car manufactured and marketed by Fiat, now in its third generation.
The first generation Fiat Panda was introduced in 1980, and was produced until 1986, receiving a facelift for 1986-2003.
The second generation, launched in 2003, was the European Car of the Year in 2004.
The third generation debuted at Frankfurt Motor Show in September 2011 and is assembled in Italy at Pomigliano d'Arco.
In 37 years Fiat has sold over 7.5 million Pandas globally, with about 4.5 million being the first series' sales."

FIAT Panda 4X4
Generations Timeline, Specs and Pictures
Generations: 3
First production year: 1986
Engines: Gasoline, Diesel
Body style: Hatchback
- 1986 - 1992
"The first 4x4 from the Panda line-up was released in 1983 and it was the first transverse-engine model with four wheel drive. The 1986 model was part of the Mark 2 in which the engine line-up was changed. Also, for the 4x4 model, the suspension remained the same because any modification would have meant a total redesign of the 4x4 system."
- 2003 - 2012
"The second generation of the Panda 4x4 was introduced in 2003 and was made available in several versions, like the Climbing and the Cross.
The Climbing has a higher ground clearance and larger wheels, but it is not equipped with a lockable differential. The Cross had a different front front end and had additional side cladding. This model did have a differential which could be locked and transmission with reductor."
- 2012 - Present
"The new Panda 4x4 is offered with a choice of two engines, an 85 hp 0.9 TwinAir turbo petrol and a 75 ho 1.3 MultiJet II diesel. Both come equipped as standard with a six-speed manual gearbox with low-range in first gear.
The power is sent to all four wheels via two viscous diffs and electronically controlled coupling. The new Fiat 4x4 also differs from the old version, in that it has standard start-stop."
