Shortened antennas with compensating coils
An antenna is intended to work in the 40-meter directional Yagi type cut to the frequency of 7,010 to 7,100 MHz, with a length of 4 meters. per element and with the deployment of a coil at 2 meters. from the center

Rotary dipole with linear load for the 40 meter band
In this article I will try to explain in the clearest and simplest way the construction of a rigid, rotating dipole with linear load for the 40 meter band. It is the self built antenna that has given me more satisfaction for its behavior, then of some years of testing and information gathered by other friends
Simple antenna for 40 meters
A antenna for 40 Meters is not very difficult.space. Only have space for a 20 Meter dipole, 33 Feet? If this is case, than you have several options
The Linear-Loaded Crappie 40mt rotatable dipole
I decided on building a rotary dipole to put at the top of the tower
The suare pole antenna
Is a 1/2-wave dipole that has been bent into a square

50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
