Modified Buddipole for 40 to 10 Meters - This is modified version of buddipole antenna, using vertical wires instead of telescopic ends by ks7j

Active receiving antennas - An active antenna is sometimes used for receiving purposes in instances where a normal antenna would be impossible to accommodate in a physical sense.

Interference Cancelling System - The use of interference signal cancellation has been around for some time. The idea is to use an auxiliary antenna almost any random length of wire in addition to the main receiving antenna

Receiving Loop Theory - N4YWK - Sensitivity of multi turn receiving loops William E. Payne, N4YWK

Antenna Polarization notes - Antenna polarization is a very important consideration when choosing and installing an antenna. Most communications systems use either vertical, horizontal or circular polarization. Knowing the difference between polarizations and how to maximize their benefit is very important to the antenna user.

9 band vertical HF antenna by RW3XA  ^pop - Simple vertical radiator with matching box. No traps, no tuner required.

VLF-LF And the Loop Aerial - The article discusses the theory of loop aerials for receiving and how they reduce the level of local noise. A Loop Aerial is described suitable for use on the LF and VLF bands together with a circuit of an interface loop tuner and preamplifier. The discussion extends to the problems of amplifier noise and the advantages of tuning the loop.
