Portable Ham Radio Antenna

Image
In this video, Julian (OH8STN) tests a new ultralight off-center-fed dipole antenna from Chameleon Antennas.  According to Julian, this field-tested antenna is "efficient, rugged, waterproof" and "lightweight." The antenna is suitable for rapid deployment at both your home station and any portable operation.

The antenna is the OCF 40 from chameleon antenna. The HF dipole is resonant on 40, 20 and 10 meters. It handles 50 watts SSB and 20 watts all other modes. Join me as we test this off center fed dipole with the Xiegu X6100 running on solar power and Icom IC-705 running an NVIS winlink session on 40 meters. 73 Julian #oh8stn ----- Thanks f

Ham Radio EME with a portable, small dish

Top Band Vertical Small Garden/Backyard Antenna

Image
Erecting a 160-Meter ("Top Band") antenna can be challenging, especially if you live on a small urban lot. In this video, Mike (M0MSN) shows us how a "DX Commander HF Antenna" and a homemade 160 Meter loading coil can get you on the air with an acceptable signal. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=VUZzjMbtg_c Here are some comments from Mike (M0MSN): HAM RADIO: Top Band Vertical Small Garden /Back Yard - 160M band DX Commander MOD. Base loading Coil for 160M Top Band. You asked me to build a small garden/ back yard Antenna for the 160M band so I used the DX Commander as the starting point. turn your 80M inverted L into a Top band antenna or use your 40M vertical. Please note that both antennas are a compromise and will not work as well as a full size antenna build for the bands. Still have fun and give it a go... Please subscribe and like. Cheers and Many thanks for watchin

10 and 15 metre QRP pedestrian mobile

Image
Summer is the perfect time to try out a pedestrian mobile ham radio station and antenna. In this video from Australian radio amateur Peter Parker (VK3YE), we see what it takes to set up a compact, lightweight pedestrian mobile station. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=Ic7MCMsl0b4. Here are a few comments from Peter (VK3YE): A summers day operating pedestrian mobile. Mostly VK2s on 10m but there's also a 15m contact.

Will it tune? Improvised Guerrilla Antennas

Image
Some day you may be forced to use an improvised antenna to get on the air.  Could you make an antenna from only the materials you find around you? Gil of the "Radio Prepper" video channel confronts that issue in this fascinating video.  Using a simple antenna transmatch (i.e. "tuner"), Gil tries a number of interesting antenna alternatives. A few of Gil's suggestions may prove useful in HOA-restricted properties as well. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=1Bt_Xk3b89A Here are a few comments from Gil: Improvised antennas can be found in the field, though they are better for reception than transmission, but contacts are possible using efficient modulation modes. Mind your safety with suspected electrified wires! https://www.patreon.com/radioprepper DISCLAIMER: The Radio Prepper logo (depicting a microphone) is indeed inspired from a famous flag created in 1775. It is NOTHING

160 Meter $39 Inverted L Antenna with home made copper coil

Image
If you need a simple, easy to build 160 meter antenna, then this idea from "Jo mf" may be worth your consideration. The "classic" Inverted L Antenna has been used for decades by radio amateurs who lack the space for a fully extended vertical or dipole for the "top band." If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=iAbWRimx1Vg Here are some comments from "Jo mf." Here is a low cost way to get on top band. this antenna costs around $40 to build. I recycled most parts. It uses elevated counterpoise radials x 4 along with a small home made inductor made from copper "ice maker" hollow 1/4 inch water line. The inductance per the online calculator is approx 6.5 micro-henries. The antenna is purposely cut to length which resonates high in the band ( 1950 khz) , and the coil is used to resonate the antenna lower in the band (CW portion, AM Fone portion etc)

Ham Radio lowest cost high performance HF antenna.

Image
If you want a low-cost, high performing HF antenna, look no further than these half-wavelength designs described by Peter Waters (G3OJV). With a little creativity, a few basic toos, and some attention to detail, you can turn ordinary wire into an effective half-wave antenna system suitable for both home and field use. If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=91l9f-nWprI Here are some comments from Peter (G3OJV): Here is an antenna system you can make for very little outlay. Versatile, Multi-Ban performance. Easily handles 100W SSB and requires no external ATU. Bend it and squeeze it into your QTH. Web Site https://hamradiostore.co.uk ----- Thanks for joining us today.
