A Ketu Yantra Matters Only After You Know Ketu's House
The diagram is for one graha. The graha is already in a house. Choose nothing until that house and its lord are named.

A diagram is not a placement
A Ketu yantra is a diagram for the south node, and it is relevant only after you know which house Ketu occupies. Ketu rules no sign. The lord of the sign it sits in is the planet the diagram cannot replace. If Ketu is in the 9th, the topic is dharma and the father-house, and the yantra is a devotional focus for that topic at most. If Ketu is in the 6th, the topic is competition and debt. Hanging the same metal square for both charts pretends the node has one life. It has the life of its house. The opposite house holds Rahu, who would want a different yantra if you were following the method strictly.
The seven years do not shrink
Ketu mahadasha lasts 7 years. A yantra on a wall does not start Venus early. If you are not in Ketu's period or in the dispositor's antardasha, the diagram is a symbol during someone else's chapter. People buy it during Saturn's 19 years because a website bundled Ketu with every malefic. Saturn is not Ketu. Saturn has its own houses and its own digbala in the 7th. A Ketu yantra during a Saturn period is a mismatched tool unless Ketu actually joins Saturn. Check the conjunction before you check the price. This page states no price and offers no installation count. Counts copied from shops are not a paddhati.
When to skip it
Skip it when Ketu's dispositor is already strong and the house is not the question you are living. Skip it when you wanted it to force a marriage or to expel a relative. The 7th lord and the 4th lord do that work, or they do not. Skip it when the seller says the square cancels Kaal Sarp. An axis of seven planets on one side is not cancelled by a diagram. If you still keep a Ketu yantra as a focus while you study the dispositor, you are using a picture as a reminder. The reminder is allowed. The promise that the node will leave the house is not. Read the house. Then decide whether a picture has any job left.
Frequently asked questions
Does a Ketu yantra remove Ketu from the 4th?
No. Ketu remains in the sign and house of the birth chart. A diagram does not edit the ephemeris.
Which planet should be read first?
The lord of the sign Ketu occupies. That dispositor delivers Ketu. The yantra does not.
Is the yantra useful in every dasha?
The node is loudest in its own 7 years and in the dispositor's periods. Outside those, another lord is the chapter.
