I was quite impressed! We are going to put up a 40 meter dipole too. Shark Antennas S-FM40 Mono Band HF 40 Meter Mini Mobile Around the late 1990's or early 2000's, I bought new from HRO, two pairs, 2 x 40 meters and 2 x 20 meters Lakeview Hamsticks - with the aim of using them mobile. 250 in. Specifications: In summary, a 40’ long capacity hat’ed rotatable dipole for 40 meters can bring a new level of low band performance to the ‘average’ ham. A series matched 40 meter antenna at either 80 or 35 feet meets the 2:1 SWR bandwidth objective, but the goal of SWR at or below I'm using them as a dipole, with the MFJ dipole bracket, feeding them with window line, and elevating the dipole about 30' into the air. They can be used with a mag mount on car roof or a portable tripod like I usually do. A ham stick dipole/vertical dipole is a less-expensive alternative compared to most of the com-mercial "rotatable" dipoles. The antenna has a pretty narrow bandwidth, as you can see from the picture attached. I work lots of DX on 20 meters. Jan 5, 2020 · I recently got the Ham It Up Upconverter for my Nooelec SDR. 1 and 0. 7. The second is to get the center of the antenna up as high as you can and pull the ends out as far as you can get them. Neat, all in black including a stealth black whip section. Consider making it a fan dipole. All of my HF antennas are being used with my main transceiver; so, I decided to install a 40m Dipole. Includes (2) WHF 40 - 40 Meter Hamsticks and (1) Hamstick Dipole Mount. A heavy duty 4 foot, 3/8 inch diamete From Irvine, California I made a couple good contacts with Truckee, California (660 miles north) and Bullhead, Arizona (362 miles east) using an Ft-891 at 10 MFJ Mini-Dipole Antennas. Several years ago I picked up pairs of hamsticks for 40, 20, 17, 15, 12, and 10 meters. The "dipole" name indicates that this antenna uses two hamsticks, one forming each side of the dipole. The ham stick dipole outperforms verticals, picks-up less noise, it’s ideal for limited space hams, and can be disassembled in seconds using quick-disconnects. 20:1. With my main transceiver, I am able to hear traffic on the 40m band day and night. Easily tunable to cover any of the 40M band, Can be mounted Horizontal or Vertical . This is a great setup to get on 20 meters when your doing SOTA/POTA or if you live in an HOA ,Apartment or Mobile home. […] Apr 10, 2002 · We put up an antenna that was made of 2 mobile antennas, 2-20 meter hamsticks, used as a dipole for 20 meters. 80 meters is a little harder to get a good SWR but that is expected. Feb 17, 2011 · There are two ways to mount the antenna. Vertical HF whip antenna for 20 or 40 metres; 10/20 metre Yagi in the attic; 40 metre loaded dipole; Multi-band Inverted L antenna; Make a rotating VHF/UHF HAM SAT antenna array; 80 metre end-fed antenna; 40m Hamstick Dipole vs 1/4 wave vertical antenna; Spectrum Communication trapped dipole 20 & 40 metres; Artificial grounding with the MFG-931 Nothing is better than wire but for a quick setup that doesn't take much time or room, this is a great alternative. In this video I review the 10, 15, 20, 40, and 75 meter Shark Hamsticks and give a solution on how to fix the poor SWR of the 40 meter Shark Hamstick. . 2 Meter Loop; UHF Yagi Base Antenna; VHF Yagi Base Antennas; Marine Antenna Mounts; MARINE ANTENNAS; MFJ PRODUCTS. Two 75-meter whips were almost three S-units (about 18 dB) below a half-wave 75-meter dipole (no wonder, since a 75-meter half wave dipole is 130 feet compared to the 16 feet of Morning, playing on 40 meter with a MFJ dipole kit. However, if the horizontal dipole is between 0. 3. 1. A fellow ham showed me how you can take 2- 20 meter hamsticks and convert them to a horizontal 20 meter dipole. 2 wavelength above ground, its impedance will be somewhat lower and closer to 50 ohms the characteristic impedance of commonly used coaxial transmission line such as RG-8, RG-8X and RG-58. This is a quick deployment to get on the air. I currently own 3 pairs of them (10/20/40m), and store them in a PVC case I made. How can we make the ham stick antenna more May 2, 2020 · I had a pair of 15 meter hamsticks, and ordered a pair for 10 meters to use with this dipole mount. 67 at 35 feet in height and 1. Jul 7, 2021 · Shark Antennas Hamsticks are mono band HF antennas that consist of a fiberglass mast with integrated coil and 48 inch stainless steel whip. 9 SWR on 10, 20 and 40 meters. Each is ruggedly constructed. With MFJ Mini Dipole Antennas, there's no reason to miss that sked on 20-meters! In fact, you may select any HF band, including 6-meter VHF, and still make your sked while camping, vacationing, away on DX-pedition, or just plain traveling. You can use any of MFJ’s HF ham sticks to make this dipo Apr 15, 2020 · Amazon. I have been able to get 1. 175 MHz (bottom of General voice): 1. I've been trying to use a pair of Hamsticks on a MFJ-347 mini dipole mount to work 40m. On 40 meters, two whips were about 1-1/2 S-units (about 10 dB) below the half-wave 40-meter dipole. The goal at the time was to use them in a dipole configuration, I got the 40M and 20M sticks sort of tuned a while back… but had not done anything with them for a while. 125 MHz (top of General data): 1. The first is to get each end up as high in the air as you can so that the antenna is a straight line (it’ll droop a bit in the middle). And when portable, I would use a matched pair to make a convenient dipole These were really well made. So… I broke out the NanoVNA, set it up for SWR and Smith Chart and tuned up the MFJ 347 Mini Dipole Mounts. On 40 meters, two whips were about 1-1/2 S-units (about 10 dB) below the half-wave 40-meter dipole. I have a 10/20/40 fan dipole in the attic and it works well. The SWR at key frequencies is: 7. 025 MHz (bottom of General data): 3. Sep 29, 2017 · The model of 40m hamstick dipole shows a resonance around 14MHz, this has to be checked with the actual antenna and if so, it can be used on both bands with just one coax run! Advertized as uniband, it is essentially (subject to test) a 40/20m multiband antenna, just like MFJ-2220 is 40m/20m/10m antenna! Here is the SWR graph for 20m: 4NEC2 MODELS Run the legs at 90 degrees and don't bend them right at the end of the house, they might interact with soffits or fascia, make the 90 degree bend one joist before that. 1-1. 1:1. 24-thread whips and you'll have an instant dipole! These mounts fit masts up to 1. 300Mhz. RW RD-40 Rotatable Diole kit. 468 / freq in Mhz = total length in feet for a half wave dipole.
