A good friend of mine and one of my antenna elmers who was a senior staff scientist worked out a calculation for this exact question. His answer for an urban environment over relatively flat ground was you will benefit from more VHF/UHF antenna height up to the point of incurring 8dB of feedline loss. Near Vertical Incidence Skywave (NVIS) is already pretty well defined in both radius and antenna height by definition. The antenna achieves best performance no more than 1/4 wavelength above the ground, and typically reaches receivers 50km-650km (30-400 miles) away. It isn't going to help you out much with receivers 1000-2000km away.

. Free Space Path Loss Calculator. The free space path loss is the loss in signal strength of a signal as it travels through free space. This value is usually calculated by discounting any obstacles or reflections that might occur in its path. IEEE defines it as "The loss between two isotropic radiators in free space, expressed as a power ratio.".

Linear Amplifiers for Ham Radio come in many size, shapes and flavors. Although nearly all modern linear amplifiers will interface seamlessly with any transceiver for running Semi-Break-In CW, very few are suitable for fast QSK CW. If you attempt to run QSK with a non-QSK amplifier and you operate a lot of CW, you will burn its T/R relay.

It is calculated by the method presented in [9], [12], that proposes modifications to the H ef f calculation in the recommendation. 2000. 7. 21. · There is no exact formula for calculating these antennas. The problem is that there are several factors that affect the antenna. Fortunately there is a starting formula for these types of antennas. For center fed, wire dipole antennas, the formula is 468/freq (mhz). Example: if you have an antenna with a 7 db gain, coax with the calculated loss (based on type, length, and operating frequency) of 2 db, and total connector losses of 1 db, you have 7-2-1 = 4 db of gain. Thus, if your rig is transmitting 100 Watts peak, you will have a peak ERP of 100 x 2.5 (multiplier) = 250 Watts.
