Transmission Line	TXLINES.EXE designs (or synthesises) and analyses nine types of transmission line. Types are : Co-axial, Square co-axial, Trough, Balanced,Wire over ground plane, Wire between ground planes, Stripline, Microstrip and Waveguide. Data on some common dielectrics are included.
Ohms Law	OHMSLAW.EXE  is a  simple programme that calculates the 12 different versions of Ohms law. OHMSLAW also includea a nearest preferred value resistor function.
RF Filters	RFFILTER.EXE  designs interdigital band-pass filters, LC nodal band-pass filters and waveguide band-pass filters, plus low-pass and high-pass filters. All filter designs can have a Butterworth or Chebyshev response
Co-ax Loss and VSWR	ANT-VSWR.EXE computes the matched loss and total loss in a length of coaxial cable for an input frequency and VSWR entered by the user. VSWR at the far end of the cable is calculated, plus VSWR for an open or short circuit termination.
dB Conversion	dBConversions include power/voltage ratios, power to dBm/dBW, noise figure/Kelvins VSWR/return loss/mismatch loss.
Folded Dipole Antenna	FOLD-DP5.EXE is a programme for calculating the feed resistance of a folded dipole given element spacing and element diameters, or the spacing for a given feed resistance and element diameters.
Gamma Match Antenna	GAMMA4.EXE is a programme for calculating gamma arm length and the required series capacitance for matching the impedance of an antenna to a co-axial transmission line.
Helical Antenna	HELIX.EXE is a design programme for axial mode helical antennas.
Tropo Scatter Propagation	TROPPO.EXE calculates the tropospheric scatter path loss at VHF and above for distances of 50-1200 km, using formulae from the ARRL UHF/Microwave Experimenter's Manual.
