In short: There is no antenna that provides you good reception, especially at HF with this dimensions, because you can't beat physics!
You can receive with everything, starting from a wet noodel cooked in salt water, a 1 ft nail for VHF and a few meter of wire for HF. If it conducts it will receive. How much signal you will receive, what is the antenna pattern in the direction of the signal and therefore how good reception will be, on the antenna design and to a very large degree on the dimensions in relation to the wavelength.
Any whip is more or less somewhat circulare in reception, meaning all directions, while LF/MF/HF Möbius Receive Antenna (Airspy YouLoop)is directional, meaning it the antenna pattern is not directed toward the signal source signal strength of the received signal will be much lower.
I looked for information on the Moonraker whip, which is advertised not only as receive, but also as transmit antenna. This makes me cautious and reminds me of snake oil you pay for the hope that you can beat physics, nothing else.
Reception between RX: 0.6-500 MHz (500 m to 0.6m) or of change in wavelength of 1:833 ratio!
Transmit TX: 3.5-460 MHz (80m to 0.652 m) still a change ratio 1:123
A Power of 10W Max AM/CW/SSB, which on HF only a small fraction will be radiated on 80 m and most of the power will be turned into heat due to losses.
Most wideband antenna designs will not exceed a 1/8 change ratio, which should give everyone a hint of how good such an antenna can perform at best.
The definition for frequency and wavelength change are
MF is the range of 0.6 to 3 MHz (1000 m wavelength) to 3 MHz (100m)
HF is the range between 3 MHz (100M wavelength) and 30 MHz (10m) while
VHF is the range between 30 MHz and 300 MHz (1m wavelength).
You require about a 1/4 of a wavelength to have a tuned/self-resonant antenna that gives you adequate reception if no obstructions conductive (metal) or otherwise are within a few wavelength to your antenna outdoor.
Indoor reception will decrease further, because of walls, floor and ceiling, and the steel reinforcements, electrical cable, water and heater pipes and so on, which will impair reception further. In short increase in losses by obstructions to make it simple.
With just a telescope whip you have adequate reception above ~100 MHz if you adjust it to be about 1/4 wavelength. The box itself should introduce losses, because the whip is connected via a tapped torroid inside the box, which will produce additional losses, , see fig.2 https://www.radioenthusiast.co.uk/artic ... -antennas/
A whip without a counter poise is incomplete without of 3 to 4 rods of the same wavelength to make it a 1/4 wavelength groundplane to give you somewhat stable conditions.
So for VHF you don’t have to spend that much money, because a whip by it itself does the same better.
On HF it is a acts as a switched coil that will provide you an “electrical extension” of the 1.3 m whip, which will provide some matching between whip and receiver. It will not increase the signal strength received by the whip, but just reduces the losses between whip and receiver to some extend. The problem is in my opinion having a toroid core material that works on such a wide frequency range.
Just having a few meter of wire works to if you connect the ground electrically to the water heater radiator or waterpipe.
The airspy loop will provide you much better reception on HF, whip a whip should work better at VHF. Aggain in my opinion there is no torroid core material that works on such a wide frequency range.
