2m 70cm antenna diy
Section 1: antenna tutorial How to build a turnstile antenna for a 70 cm band (~435 Mhz)? Materials: pipe for the body - I used casual hydraulic PCV from the construction shop; holders for the rods - for me, the 3D print from ABS was the most convenient (if you want to reuse the project, you can find it on GitHub)I used 1″ thin-wall PVC pipe, aluminum tape, and RG-8X coax. The goal here is to put up a cheap, easy, and quick 2-meter antenna that is simple and unobtrusive, but works quite well. If you have the materials handy, you can build and install this antenna in a couple hours. This dipole was constructed as follows: Cut 6 or 7 feet of 1″ thin ...HYS 771Q 2m/70cm SMA-M Tactical Antenna Dual Band Foldable Portable Aerial Compatible with BF-UV3R YAESU VX-1R VX-2R VX-3R TYT 2 Way Radio (Camouflage) 1. £899.

This set me back about 50 euro cents per 2 meter (which means about 0.65 USD for 6.6 feet). I needed 50 cm of pipe in this antenna (2 times 25 cm). Next to this I used 70cm of speaker wire I had laying around and a few tie raps to strap it all together. I checked the SWR with the build in SWR meter of my FT-817. It was all 1:1.1 so perfect!The SWR on 2m is 1.6 @ 144mhz and 2.2 @ 148 mhz following your measurements. Although I can not get anything out of the 70cm side. There is a repeater I can open with a HT with a rubber ducky antenna standing at the antenna location but it will not open it up through the antenna.. I do not have the equipment to check the SWR @ 70cm though. ….
