X-Beam antennas - Two element X-Beam is a high-performance broad-band antenna that is ideal for Ham radio operators with limited space. X-Beams are inexpensive and easy to build. The performance of the simple X-beam is amazingly similar to larger, more conventional antennas by 4S7NR

Slim Jim 2m Vertical - This VHF 145 MHz antenna is easy to build and with no radials. It shows equal gain of 5/8 lambda. It is light weight, you can hang it somewhere (on a tree may be) and work.

80 meters Short Dipole - The best antenna is the simple Dipole. If you have height, you even can put up a quarter wave vertical or an inverted, but sometimes you may need shorten version by 4S7NR
