Re: [HamBrewers] Question on Loop/ Delta Loop

Madhukarji - try this link, i installed a loop in my previous qth on ideas mentioned here. though a full wave loop is difficult considering the real estate requirements in city scenarios, you can always try something. to reduce the noise.

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.
