1 Cover the cannula site with sterile transparent semipermeable occlusive dressing (e.g. Tegaderm, IV 3000) placed aseptically over the catheter. 2  If desired, place sterile tape over the hub and wings of the device before placing the transparent dressing.
Quick Answer. The difference between a long and short wavelength is the distance between two identical points on successive waves. Wavelength is also characteristic of the energy level of a particular wave, with shorter wavelengths being more energetic than longer ones. Continue Reading.
A: The most obvious difference between VHF and UHF antennas is the size. A half wave dipole for channel 2 will be 10 times longer than for channel 28. This means that a much more elaborate UHF antenna can be constructed without the antenna becoming physically unmanageable.
