I plan on building single antennas on 2m (10 elements +) and 70cm (14 elements +) for SSB and either singles for FM or perhaps co-phased, not sure yet. I'm ...Just got my General license to operate on the entire 10 meter band, so I went for a four band antenna such as this and gave it a shot. it's useable on 70cm except near the end of the band, useable on the entire 2m band, but it's not very efficient, useable towards the CW portion as a terrible 6m antenna, and a very narrow bandwidth on 10m ...Easy 2 meter SSB Loop Antenna.

As soon as I got my Technician’s license and my first radio (a Yaesu FT-70DR ), I set out to build one of the VHF / UHF (2m / 70cm) tape measure Yagi antennas I had been reading about online. This video got me started with measurements for the tape, etc.$\begingroup$ I have been exploring building a parabolic 2m/70cm. There is a very interesting antenna design built specifically for stealth(HOA). My use case is EMCOMM/ARES/RACES. Its referred to as a slot antenna. My research just started, so I will share a link to get you started.Here is a simple 2-element quad for 2m that is easy to build and does a good job. It works well for extending the range of an HT, transmitter hunting, SSB, or general use. When not in use it comes apart for storage. The SWR is less than 1.5 : 1 across the band from 144 to 148 MHz without any tuning. The boom can be rotated for …This is a really easy, fun antenna to build.

Consider two dipoles, cut for 20 and 10 meters. We can easily use both dipoles with a common feedpoint. The reason is fairly simple: when one dipole shows a low impedance, the other shows a high impedance.Don't worry about it. In a general purpose FM antenna, little bit of feedline radiation can be even useful, makes it work better against horizontal antennas. A sleeve balun could be an option. Thick tube (1inch or more) over the coax, open at feedpoint, shorted to coax shield at far end, 1/4 wavelengths long at 2m, 3/4 waves at 70cm.A 2M/70Cm antenna should cover the popular 2 Meter VHF and 70CM UHF bands.

Dual band antenna 2m 70cm applications: The big wheel is a horizontal polarized omni directional antenna. Perfect gain and swr on both bands. 2m shows a 38.5in driven element but with the bent part the wire would be 57.75in long? It's a really great omni antenna for the 2m band. Source: img.17qq.com. Stacking of big wheel antennas to achieve a ...A ground plane antenna for 2m or 70cm is one of the simplest antennas to build and get working, and it can work quite well for repeater or simplex operation. It is easy to build for other bands as well. I’ll show you several different construction methods that you can use, based on the materials you have available.Here i present the measured SWR of the antenna. As you can see, the impedance of the antenna is very well matched to a 50 ohm system. Between 144 MHz and 146 MHz, antenna has an SWR less than 1.2 . For an SWR of 2, the antenna has a bandwidth from 138 MHz to 151 MHz which is a pretty good result. F4HWK
