Sections together, and the 15 meter stub resonator wire was re-strung Terrace, where the last 2 bolts were inserted to hold the middle Sections at convenient points and carried it up one by one to the
Stairwell to the roof! So, I partially disassembled it temporarily into the antenna is too large to get out theĭoor, around the hallway corners, and up the The micro-fibres while looking closely under an illuminated magnifyingĪs I found out, after assembling all the resonators and putting the Part of the 4 hours of assembly time, was spent with tweezers removing Glass slivers to be embedded in one's fingers and hands. Handling of the fibreglass insulators, because these may cause tiny Special attention needs to be paid to the burrs and particularly The aluminum coil resonator contraptions are added one by one to theĪluminum tubing sections, and bolted in place. Instructions carefully, and matching the parts up to the description It took about 4 hours to put together, following the Still waiting for the tripod kit to arrive.īut in the mean time, I assembled the antenna in my workshop and I received the antenna in the first shipment, but I'm Tried and proven, IĪfter a friend picked up a Butternut HF9V antenna at an HRO storeĪnd sent it to me, I ordered the companion tripod roof mount with With the basic construction relatively unchanged.
That this line of antennas has been in production for almost 30 years, Recent satisfied reviews of the Butternut model HF9V, and realized Principle of instantaneous all-band operation is the same. Was way before ALE was widely used on HF, but the need for this basic I was really impressed back then with the elegant design and practicalĪspect of being able to change to any band and just start talking. Then, after reading one review, I recalled my earlier experience yearsĪgo, in 1980, when I put up what was then a strange new multi-band a resonant vertical with coverage of theĨ0-40-20-30-20-15-12-10 meter ham bands, without need for a tuner. Reviews written by hams who had been using various brands of verticals.īut, I found very few antennas out there that met the one key The internet to see what commercial antennas exist, I began reading Look for a commercial antenna rather than succumbing to my engineering gut instinct to redesign the wheel and build one from scratch. Given the fact that the season has had someĪnd my work schedule left little time for antenna work, I decided to The choices all pointed to an HF ham-band ground-plane vertical on top HF bands, a minimum of roof space, and survivability in the bad weather The trick is toĬombine this with DX take-off angle high-efficiency on all the higher Signal, more effective radiated power would be needed. To cover this remote area of the world with a better transmit Station performance and coverage area could be increased at the same In a typhoon while I'm away from the station on a business trip.Īt first, I started to think about installing a back-up antenna -possibly a vertical- thatĬould be switched over to, if the broadband dipole came down Then, I became attracted to the idea that the That one of the trees that supports the end of it could be blown over This sort of workhorse antenna is great for ALE but watching the dipole danceĪround like a crazed deadhead in the recent storms, made me a bit concerned Receive performance on the broadband dipole is good, but the transmitĮffectiveness for low angle DX is somewhat less than optimum. Little negative gain to achieve a DC to light match to 50 ohms. Prior to this, I've been using a stout dipole broadband coaxial antenna system
HFĪntennas here must be durable, or they simply will not survive. Weather and fierce gusts every year in this Pacific coastal zone. My experiences selecting it, assembling it, putting it up, tuning theĪntenna, and how it performs on the air for 80m-10m ALE operation. Vertical to cover the HF ham- bands- only. Potential for ham radio ALE station operators as an efficient Time, my initial impression is that I believe it has excellent Provides low SWR on ALL the HF ham bands, good RF efficiency, durable construction, light weight, with convenient installation. Butternut HF9V Vertical as a Ham Radio ALE Antennaīenefits to the ham radio ALE operator: No tuner needed.
