- Yes the efficiency on 80m may be too low, because of small size. - Adding center extenders could help but then 75m hamsticks are out of 80m band - By using 40m hamsticks and maybe center loading coil and extenders tuning to 80m possible? - Then also operating on 40m without extenders OK - 80 operation only needed for domestic qsos, no DX - On 30m and 20m hamstick dipole would work OK Any comments on these? 73 Jouko OH5RM Ok, the antenna is portable. Toss a wire over a couple of tree limbs and either use full-sized 80 meter dipole, or load it with loading coils. If you load the antenna with coils located at the end point of 40 meters, you may find yourself with a dual band antenna -- 40/80. Since you are operating primarily local 80 meter operation, any height above ground up to about 20 feet will result in NVIS, pretty good signal there. You could also try a tree-limb somewhat vertical. Drop a short ground rod into the ground, tap shield to that and toss other end of 65 foot wire (plus or minus) over a tree limb. It will operate, but not perfect. However, it should work as well or better than the hamsticks. Just another thot Buck -- 73 for now Buck, N4PGW www.lumpuckeroo.com "Small - broadband - efficient: pick any two." |
