- Extended Double Zepp Antenna for 17 m
- 17 meters band version of an extended double zepp antenna.
The Zepp, short for Zeppelin is any resonant antenna end-fed by ladder line. A Double Zepp means a center-fed antenna. This extended version provides 3 db gain over a dipole. The double Zepp consists of two collinear 0.64 wave length elements fed in phase

- QM5 Yagi for 2 meters band
- The QM5 antenna is a simple 5 elements Yagi with 1.88 m boom length for the lower 144 MHz SSB/MGM band, I used it mainly for Sporadic-E and MS contacts. It exhibits a forward gain of 9.17 dBd; i.e. 11.3 dB forward gain over the isotropic radiator, while the F/R is about 11.5 dB. Elements

- The QM7 antenna is a simple 7 elements Yagi with 3.70 m boom length for the lower 144 MHz SSB/MGM band, used it mainly for Sporadic-E and MS contacts. It exhibits a forward gain of 11.35 dBd; i.e. 13.5 dB forward gain over the isotropic radiator, while the F/R is about 12.5 dB
[ Hits: 4702 | Votes: 12 | Rate: 5.75] - 2 Meter 10 Element Quagi Antenna
- This antenna was designed by N6JSX Kuby for Transmitter hiding. Fitting the requirements of directionality, high gain, and portability. This antenna was derived from the ARRL Handbook information on Quagi's and Yagi's; in the absence of two meter Quagi information, UHF Quagi dimensions were scaled into 146 MHz use.
[ Hits: 8408 | Votes: 8 | Rate: 7.25] - 2m VHF antennas with high gain
- 2m SSB/CW-12.5 Ohm Yagis with extrem high gain and small bandwidth.
These Yagis were constructed as ultra-light, portable Yagis with extrem high gain. They have small bandwidth and are working from 144,0-144,8MHz with good SWR.
[ Hits: 6000 | Votes: 7 | Rate: 8.43] - ZR6KMD 2M Beam Antenna
- This design was adapted from an article in the ARRL Handbook and built with simplicity and
duplicity in mind. This antenna is a vast improvement over a standard dipole with a forward gain of around 8db with a front to back ratio of 10db.

- The gain of aerials: the myths explained
- In the long history of beam aerials there has persistently existed the claim that certain types of aerials perform better than yagis.
[ Hits: 1338 | Votes: 1 | Rate: 10.00] - Antenna Gain on Trial
- Most people think it's a good thing to have and the more the better. However, this is not always true - and the amount of gain is often not what it appears to be. Assuming higher gain is what you need, how do you determine what will give the best performance?

[ Hits: 1978 | Votes: 7 | Rate: 5.43] Technical Reference : Radio Frequency Interference : Noise Reduction
- Antenna Noise and Signal Cancelling at LF
- By using the signals from two antennas, controlling their relative amplitudes and controlling the phase of one of them, unwanted signal or unwanted noise can be phased out. Circuitry is described which uses the signal from a wire antenna to provide selective cancelling against the signal output from an LF loop antenna.
