I recently acquired a set of mono band Hustler mobile antennas covering 80M, 40M, 20M, 17M and 15M.Over the weekend I got the opportunity to try the 40M Hustler antenna whilst parked up at 1175 feet on top of neighboring ILKLEY Moor. The antenna was pulling in some big signals and putting out a rather nice footprint as I worked a handful of Irish Stations as well as a couple of Europeans.I made a quick video of the new Hustler mobile antenna in action on 40M with the help of camera Woman Louise – M3TLL (My lovely YL). The latest Video can be seen below.
I am looking forward to testing the rest of the Hustler Mono Banders as soon as possible! Thanks for the visit, 73.
Hi Tony I have since changed vehicles but still have the antenna. I don't need any atu all top sections are resonant with decent band width. My antenna mount is fixed to the roof with a hole through but I used brackets fixed to the roof bars in previous installations. I aways run a separate earth/grounding wire from the Base of the mount direct to the nearest bolt connected to the vehicle chassis/body. Hope this helps. Best 73 Simon M0YKS
I came across a simple delta loop design courtesy of dxzone found on the net some time ago and have been planning to give it a go for a while. This weekend I had a couple of hours spare, so I decided to give it a go using some 2mm multi strand wire cable, a dipole centre and a mixture of 75 ohm and 50 ohm coaxial cable. The delta loop is supposed to be resonant on 20 meters but I found it to be a little high so at present I am tuning the Loop with my mfj-969 which copes extremely well. The resonant frequency is 13.2 MHz at the moment so the next chance I get, I shall shorten the overall length making sure that each of the three sides are still equal in length, and hopefully adjusting the antenna for maximum performance ATU free for 14.2 MHz. I believe the miscalculation in the resonant length is probably down to the fact that my wire is covered in the plastic sleeving from the manufacturer which always effects the swr as I have noticed in past experiments with dipoles you always get sl...
This Antenna design was one that I used about 4 years ago, it worked exceptionally well on 80m and 40m. The size of the antenna makes a Half wave length on 80 meters, and with the traps a half wave on 40m with a SWR (standing wave ratio) of 1:1-1.5 across both bands. It worked well also on 20m with the use of an A.T.U (antenna tuning unit). I made my version of this antenna using 3mm multi strand copper cable which I left covered by the PVC insulation. The traps can either be home brewed using some 40mm diameter plastic drain pipe and winding wire around the pipe approximately 10 turns, then connected in line after the 10 metre lengths. Or the alternative is to purchase some commercially made 7.1 MHz traps, and fit them in line the same way. The antenna can be fed with 50 ohm coax with a home brew balan or again a commercially purchased balan. The wire lengths of the dipole are 2x 10 metres and 2x 6.7 metres as shown on the diagram above. This antenna can be mounted quite low to the gr...
FT-890 & Recent Delta Loop Experiment: I have owned my Yaesu FT-890 since 2002 and have enjoyed years of reliable service. A couple of months ago you may recall that I recently reinstated the FT-890 as a second set up allowing operation from our dining room as well as my regular shack. I have since worked a good page and a half of paper logged QSO's into places like the Middle East, The US and EU as well as across Russia. I have been using the homemade 20m Delta Loop that I recently made and installed which is performing very well on 20m. The delta loop works well on 17m, 15m, 12m and 10m with the help of an old Nevada TM1000 manual antenna tuning unit.This week I managed to get into a couple of US repeaters up on 29Mhz using the FT-890 and Delta Loop which is pretty cool. Frequency Drift: Whilst enjoying my old rig I discovered that it had developed an error and occasionally would drift up and down frequency both RXing and TXing. The drifting in frequency seeme...
