    Default Help me choose HF antenna - restricted space

    Hi guys, having moved a couple of years ago I now have a bit of outdoor space. Its a townhouse with communal garden and garage area at the rear. I need to put up a discreet hf antenna, open to suggestions.

    I have just ordered a winch to fit to the pole of the that supports my VHF/UHF antenna plus some rope.

    Current I do have a 40/20 dipole made of ladder feeder but this might not be very practicle to mount due to the ladder. The front to back measurements of the house are about 10M I think, some pics are below. I plan on mounting the ends with large hanging baskets brackets and having the aerial in an inverted V shape. How does this sound? As you can see I am against a chalk cliff, I am very low down compared to surrounding land!

    My main bands I'd like are 10M, 15M&17M(if possible) and 20m. I'd rather not use a tuner, but I could start off using my IC7000 and the matching tuner, long term I want to go back to my 706 Mk2 and I could purchase a tuner if needed.

    Needs to be fed with coax.

    Thanks and 73s!

    James,

    I am playing around with the MFJ-2240 portable dipole for 40 M and so far so good and they make them for the bands you are interested in. It was a bear to get tuned in but once there I have an SWR of about 1.54 centered on 7.190. I would say it's biggest drawback is very narrow bandwidth.

    Do you have access/permission to use the trees on the bluff? That might be the ticket for a fan dipole.

    Umm, i don't and i'd prefer to just run the dipole parallel with the house to keep it discreet. At the moment I think the https://www.wireantennas.co.uk/zs6bkw-jr.html fits my needs and with drooping the ends down a bit, should fit in.

    The centre would be supported by a pully on the pole, then some sort of stand offs on the wall to support the ends or steaks in the ground.

    Chameleon CHA-HYBRID and 66' of wire. Will work even laid across the roof.
