Many models will be detailed and construction information for all will be included within the article. One important note is not all will be re-published anywhere else so if you want one like this, you may just have to subscribe to DUBUS!

Yes, you are reading that right, 15.1dBi from this 10el 50MHz LFA

Furthermore, the article will discuss the additional findings and many results that have been established over the last few months.  Where is the best feedpoint, is it the front or back of the loop? Is there an easy way to make the LFA loop? These will be answered and more.

An SWR higher than 1.1:1 just would not be acceptable wth an LFA!

As always, all of the LFA's featured are all 50 Ohm direct feed antennas, no matching arrangements required! If that lot is not enough, many new 144MHz designs will be discussed and compared with existing antennas within Issue 4 of DUBUS later this year.

Build information will be provided for this 144MHz 8 element LFA Yagi which is shorter than the DK7ZB equivlant, higher in gain than the YU7EF, has no matching losses (50 Ohm direct feed) and super low-noise. In fact, when compared with traditional Yagi antennas of the same or similar boom length (VE7BQH G/T list), no other antenna comes close to sky temperature or G/T figures on any of the antennas featured in issue 4. Many more LFA's will be featured in this issue including EME arrays with best ever 4 Bay sky temperature and G/T figures!

Take off .2dB matching losses and you have the same gain, smaller boom and cleaner pattern

So if you have antenna projects in mind for those long winter months,  subscribe to DUBUS and get all the information you need and become apart of the LFA revolution!
