Hi,
If your transceiver has a RX antenna input or if you are able to modify it, a receiving only antenna could be a nice solution.
You can keep an efficient TX antenna and reduce the noise level.

I face a very high level of electrical noise at my new Permanent QTH - being just about 300 Mtrs from HT Lines - becoming a Permanent QRM too!!This is present at unacceptable levels - s-9 + most of the times. This made me consider a Loop/Delta Loop Antenna for 7 Mhz to handle the noise issue.Planning for a Horizontal installation - I understand that this gives me only Ground Waves - OK for now.I need clarifications on the following issues.1. Most of the Links that I see on the web is for a full wave design. What limits the use of a Half Wave Delta Loop??2. Where should bthe feedpoint be?3. What will be feedline impedence??4. What kind of Balun is required to feed to a 50 Ohm cable?5. What else is to be considered??I have a LDG - Z-100 Plus antenna tuner.Madhukar – VU2MUD
