This is the antenna for you guys who want to get on HF effectively, and haven&x27;t too much space or cash to throw around. Actually, it&x27;s a design from ZS6BKW (aka G0GSF), similar to the G5RV, but it actually resonates on five bands, (well 6, actually) and doesn&x27;t rely on a tuner (ATU) to make it work. The design appeared in TT (RadCom) Jan.

The telescopic antenna can be physically extended or retracted to get resonance at any frequency between 14.000 MHz and 29.700MHz. VSWR 11 on all bands. My antenna supported in it&x27;s wooden box, ready for portable operation. So my portable antenna needs no guy ropes and covers 3.5MHz to 29.7MHz without any Antenna Tuning Unit at all.

This multiband antenna covers the 80, 40, 30, 20, 17, 15, 12, 10 and 6 Mx Amateur bands. Multiband operation is achieved by use of 300 ohm balanced line fed to an antenna tuner. This loop antenna needs to be run in the horizontal plane. ie. parallel to the ground. The formula used to determine fundamental frequency wire length is - Length. The SWR can be adjusted by moving the driven element slightly up or down the boom or playing with the gap size between the two dipoles. All elements are mounted to the boom with U Bolts except for the driven element which is isolated from the boom. The Bazooka sleeve is also grounded to the boom.

SWR on the low bands dropped and the model showed that the electrical efficiency increase to about 80 rather than 40 on the 160m band. Efficiency is >95 on 80m and even better on 40m with the new ferrite according to the model. The bands needed another alignment adjustment with the big ferrite installed. PART - 1 The EFHW antenna as a radiating and receiving element is a decent multi-band antenna with good efficiency on all bands, provided it is driven at its feed-point using a well configured and well-matched driving source. However, it has its idiosyncrasies. The radiation pattern of this antenna on most bands produces multiple lobes.

A convenient coil size is 2-12 inches in diameter, six turns per inch, such as B & W 3905-1 stock. The number of turns required, assuming 80 meters as the lowest band to be used, should be about 30 turns with an antenna length of 25 feet. Adjustment of the antenna requires the use of an SWR bridge. This HOA Buster is a HF base antenna that defeats the rules imposed upon amateur ham radio operators by using existing metal (aluminum or steel) gutters as an antenna,.

This assumes that you use only antennas with a 21 frequency ratio. In other words, do NOT try to add to a 80402010 any other antennas. Specifically do NOT install a 15 meter wire or you will mess up 20 and 10. Also, do NOT add 60 or 30 meters to a 804020 multiband antenna; do a separate multiband antenna with its own feedline for that..
