https://stream.echo6.co/videos/watch/cc0d80c5-b00a-4d5e-a5c3-8e64fd6ed3bc A 7 MHz dipole made to operate on 3.5 MHz by adding end loading coils. It won't be as efficient as a full sized 80m dipole and the bandwidth will be narrow. However it will get you on the air from a small yard. The antenna here was inspired by and is very similar to VK5AH's 4 band dipole (website http://users.picknowl.com.au/~wavetel/antennas.htm#4bandHF or https://ftp.unpad.ac.id/orari/library/library-sw-hw/amateur-radio/ant/docs/VK5AH%204%20Bander.htm ). The only thing that's different with mine is that it has a dipole for 10 metres (not 15 metres) and I didn't use a balun. Coil dimensions: 115 turns of medium sized insulated hook up wire on 40 mm plastic pipe close wound. Length of coil about 250mm - cut your pipe for 270 and preferably 290 mm to allow room for wire thickness variations.
